2007 Buick Trucks Tire Fitment Guide

2007 Buick Trucks vehicles use two different tire sizes depending on model. The Rainier uses 245/65R17, while the Rendezvous uses 225/60R17. Both sizes fit 17-inch wheels, but they are not interchangeable year-make-wide sizes because each one belongs to a specific model. The 245/65R17 product fits a 7.0- to 8.0-inch rim width range, and the 225/60R17 product fits a 6.5-inch wheel.

That means the first fitment question is model identification, not just year and make. Once you know whether you have a Rainier or a Rendezvous, you can move on to wheel width, sidewall style, and intended use. If the vehicle has aftermarket wheels, confirm the actual wheel width and the size currently mounted before replacing anything.

On a 2007 Buick Trucks Rainier, 245/65R17 is a metric radial size. The 245 is the nominal section width in millimeters, 65 is the aspect ratio, R means radial construction, and 17 is the wheel diameter in inches. In the available Rainier fitment, this size carries an S speed rating, which means a 112 mph maximum rating, and the tire uses an RWL sidewall.

For a Rainier owner, that code tells you the tire is built around a relatively broad SUV-size footprint on a 17-inch wheel. It is not simply a cosmetic variation of the Rendezvous tire. If your sidewall currently shows 245/65R17, stay with that size unless you are intentionally reengineering the wheel-and-tire package and have confirmed all clearances and wheel dimensions.

On a 2007 Buick Trucks Rendezvous, 225/60R17 is also a metric radial size. The 225 is the nominal section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. The available tire in this size carries a T speed rating, which means a 118 mph maximum rating, and it comes with a narrow whitewall sidewall.

That code points to a narrower, lower-profile 17-inch fitment than the Rainier uses. For many Rendezvous owners, the practical appeal is that the proper size can also preserve a more Buick-like visual character when paired with a whitewall radial. Check the actual sidewall on the vehicle and verify the wheel before replacing one tire or a full set.

No. The 2007 Buick Trucks Rainier uses 245/65R17, and the 2007 Buick Trucks Rendezvous uses 225/60R17. Both are radial 17-inch sizes, but they serve different models and should not be treated as one shared Buick Trucks fitment for the year. The available Rainier tire also differs in sidewall style and load rating from the available Rendezvous tire.

That split matters because a buyer who only knows the year and make can easily end up looking at the wrong tire. The safe approach is to confirm the model name on the vehicle, then compare the sidewall marking already on the tire with the wheel dimensions actually fitted. Model-specific fitment is the starting point before considering appearance or driving use.

2007 Buick Trucks tires are available in two very different sidewall looks. The 245/65R17 Rainier fitment comes with an RWL, or raised white letter, sidewall from BFGoodrich. The 225/60R17 Rendezvous fitment comes with a narrow whitewall from Travelstar. Both are radial tires, but the visual effect is markedly different from one model to the other.

For owners who care about appearance as much as size, that distinction can help guide the right choice once the model is confirmed. Raised white letters lean toward an SUV and light-truck look, while a narrow whitewall feels more in keeping with Buick tradition on a crossover or family-oriented vehicle. If presentation matters, match the sidewall style to the vehicle's character as well as the correct size.

Two brands cover the available 2007 Buick Trucks fitments here. BFGoodrich covers the 245/65R17 Rainier size with the All-Terrain T/A KO2, while Travelstar covers the 225/60R17 Rendezvous size with the UN106 radial in a 9mm narrow whitewall configuration. Each brand is tied to a different model-specific size rather than offering direct overlap in the same fitment.

That means brand choice follows the model and size first, not the other way around. Rainier owners looking at a more truck-flavored tire character will be in a different lane than Rendezvous owners trying to preserve a more traditional Buick appearance. Start by matching the tire size on your vehicle, then evaluate whether the available brand and sidewall style suit how you use and present the vehicle.

The two 2007 Buick Trucks sizes both fit 17-inch wheels, but their wheel width requirements differ. The 245/65R17 tire used on the Rainier fits a 7.0- to 8.0-inch rim width range. The 225/60R17 tire used on the Rendezvous fits a 6.5-inch wheel. Rim diameter and rim width both matter when matching a tire to the wheel.

That is especially important on used vehicles, where replacement wheels may not be original. A 17-inch diameter match alone does not guarantee the wheel is correct for the tire you want to run. Before replacing tires, confirm the actual wheel width stamped on the wheel or measured directly, then match that number to the tire size intended for your specific model.

The available 2007 Buick Trucks fitments are modern radial tires in 17-inch sizes, and neither tire shows a tube-type marking in its size description. That points to standard tubeless radial use on appropriate wheels rather than a tube-type collector fitment. As with any modern radial application, the wheel condition and valve stem matter just as much as the tire itself.

For most Rainier and Rendezvous owners, the practical concern is making sure the wheel bead area is clean and the valve stems are in good condition whenever tires are replaced. If an older wheel has damage, corrosion, or prior repair work, have it inspected before mounting a new tire. A sound tubeless setup starts with the wheel, not only the sidewall marking.

Both 2007 Buick Trucks tire sizes use a 17-inch rim diameter, so the wheel diameter itself is common across the Rainier and Rendezvous. That does not automatically make the wheels interchangeable, because the 245/65R17 Rainier tire is intended for a wider rim range than the 225/60R17 Rendezvous tire. Width suitability still has to be confirmed before swapping sizes.

In practical terms, sharing a 17-inch diameter is only the first checkpoint. If a vehicle still has its original wheels, the correct size is usually the one tied to that model. If the wheels have been changed, verify wheel width and overall clearance before assuming either size can be used. Diameter compatibility is not the same thing as full fitment compatibility.

A 2007 Buick Trucks vehicle should be stored away from direct sunlight, standing moisture, and ozone sources such as electric motors, battery tenders, welders, and compressors. Keep the tires inflated to the pressure you use for storage, and move the vehicle periodically so the same footprint is not loaded for months at a time. Clean, dry storage does more for tire life than heavy dressing products.

Rainier and Rendezvous models both use modern radial tires, so they generally tolerate inactivity better than older bias-ply designs, but long static storage still ages rubber. If the vehicle sits for an extended season, rolling it occasionally or supporting it properly can help reduce flat spotting and sidewall stress. Tire covers are helpful when the vehicle must be stored where light exposure cannot be fully avoided.

On a 2007 Buick Trucks vehicle, tire age is usually more important than mileage once the vehicle becomes a low-use second car or collector-kept SUV. A good rule is to begin evaluating tires closely around five to seven years of age and to treat around ten years as the point where replacement deserves serious consideration, regardless of remaining tread. The DOT date code on the sidewall is the key age marker to read.

That matters because a Rainier or Rendezvous can look lightly used while still riding on old rubber. Sidewall cracking, hardening, irregular wear, or a tire that no longer holds pressure well are stronger warning signs than tread depth alone. If the tires are several years old and the vehicle is being returned to regular road use, replacing aged tires is often the smarter move than trying to stretch service life.

Tires on a 2007 Buick Trucks vehicle should be checked before every drive and given a more thorough inspection before any extended trip. Look for sidewall cracking, weathering, punctures, bulges, uneven tread wear, and signs that pressure is drifting down between uses. Also inspect valve stems closely, since aging stems are a common weak point on vehicles that sit for long periods.

That quick habit matters even more on older daily drivers and low-mileage family vehicles that may spend weeks parked between outings. A simple walkaround can catch issues before they become a vibration, a roadside flat, or a heat-related failure at speed. If the steering feel changes, the vehicle pulls, or the tire shoulders show unusual wear, have alignment and suspension condition checked along with the tires.

The available 2007 Buick Trucks tires are modern radial designs with highway-capable speed ratings. The 245/65R17 Rainier tire carries an S rating, which corresponds to 112 mph, and the 225/60R17 Rendezvous tire carries a T rating, which corresponds to 118 mph. Those ratings are well above normal U.S. highway speeds, assuming the tires are in good condition, correctly inflated, and properly matched to the wheel.

Real-world safety still depends on the condition of the entire vehicle. On a used Rainier or Rendezvous, brake condition, suspension wear, alignment, and tire age matter at least as much as the letter on the sidewall. If the tires are old, cracked, unevenly worn, or underinflated, the speed rating becomes irrelevant. A fresh inspection before regular highway use is the right place to start.

The available 2007 Buick Trucks tires show different maximum load and pressure figures by size. The 245/65R17 Rainier tire is rated at 2,405 pounds at 65 psi, while the 225/60R17 Rendezvous tire is rated at 1,709 pounds at 44 psi. Those are tire maximum figures tied to the tire's own load rating, not a blanket recommendation to inflate every vehicle to those numbers for normal driving.

For actual service pressure, start with the factory vehicle placard or owner's manual for your specific model, then compare that with the tire manufacturer's guidance for the tire you are using. Do not transfer a pressure figure from the Rainier size to the Rendezvous size or the other way around. Correct inflation depends on the exact tire, wheel, and vehicle application working together.

Before a longer trip in a 2007 Buick Trucks vehicle, inspect all four tires and the spare for cracking, cuts, punctures, bulges, abnormal wear, and proper inflation. Confirm the valve stems are sound, the tread is even, and the tire age is still reasonable for highway use. It is also wise to make sure the wheel lug torque, alignment feel, and ride quality have not changed since the vehicle was last driven.

Tire condition is only one part of the checklist on a vehicle of this age. Long-drive preparation should also include brakes, fluids, lights, suspension condition, and a quick look underneath for leaks or loose components. If the vehicle has spent a long time parked, take a shorter local drive first to settle the tires and confirm there are no vibrations, pulls, or pressure-loss issues before committing to distance.
