2007 Acura Tire Fitment Guide

2007 Acura vehicles use five distinct tire sizes across three models. The RL uses 245/50R17 or 245-680R460, the TL uses 235/45R17 or 235/40R18, and the TSX uses 215/50R17. Among the sizes with current product coverage, 235/45R17 fits 17-inch rims in the 7.5 to 9.0 inch range, 235/40R18 fits 18-inch rims in the 8.0 to 9.5 inch range, and 215/50R17 fits 17-inch rims in the 6.0 to 7.5 inch range.

The practical takeaway is that 2007 Acura fitment is model-specific, and in some cases wheel-package-specific, rather than interchangeable across the lineup. Start by identifying whether you have an RL, TL, or TSX, then confirm the wheel diameter stamped on the wheel or printed on the tire already on the car. That step matters especially on the RL, where one fitment uses a conventional 17-inch wheel and the other uses a metric-diameter wheel.

245-680R460 is a metric radial size used on some 2007 Acura RL models. The 245 refers to section width in millimeters, 680 is the tire’s overall diameter in millimeters, the R indicates radial construction, and 460 is the rim diameter in millimeters. Unlike a standard inch-based size such as 245/50R17, this format pairs only with a matching metric-diameter wheel.

That difference is important because a 460-millimeter wheel is not interchangeable with a 17-inch wheel, even though the dimensions may look close at a glance. If your RL carries this metric size, confirm the wheel itself before ordering anything. Owners often encounter this issue when a car has been converted from one wheel system to another, so checking the actual wheel on the car avoids an expensive mismatch.

No. 2007 Acura models do not share one universal tire size. The RL uses 245/50R17 or 245-680R460, the TL uses 235/45R17 or 235/40R18, and the TSX uses 215/50R17. Even where two models use 17-inch wheels, the tire widths and aspect ratios are different, so the sizes are not direct substitutes.

That means year and make alone are not enough to choose correctly for a 2007 Acura. Model identification comes first, and then wheel diameter confirms which branch of fitment applies. If the car has aftermarket wheels, compare the existing tire size and wheel markings against the original fitment before making a final choice. This is especially worthwhile on the TL, where both 17-inch and 18-inch fitments were used.

The current product range for covered 2007 Acura sizes centers on blackwall radial tires. Blackwall options are available in 235/45R17 for the TL, 235/40R18 for the TL, and 215/50R17 for the TSX. That look fits the original character of a 2007 Acura well, since these cars came from the modern sport-luxury era rather than the wide-white or vintage sidewall eras.

For most owners, sidewall choice here is less about period restoration debate and more about selecting the right performance-oriented radial in the correct size. A clean blackwall keeps the appearance closest to what these sedans would have worn when new. Once the correct size is settled, the finer comparison usually comes down to brand, load specification, and speed rating rather than sidewall styling.

BFGoodrich and Nitto cover the product range shown for 2007 Acura fitments. The TL’s 235/45R17 and 235/40R18 sizes are available from both BFGoodrich and Nitto, while the TSX’s 215/50R17 size is covered by BFGoodrich. Within BFGoodrich, the g-Force Sport Comp-2, g-Force Comp-2 A/S, and g-Force Phenom T/A appear across the supported sizes.

That mix gives 2007 Acura owners a selection of modern radial products from established performance-oriented brands rather than a single-source option. If your priority is staying with a familiar performance name, either brand can satisfy that on the TL sizes. For the TSX size shown here, BFGoodrich is the path to compare first, while RL owners should confirm wheel type and then move to the model-specific size page for the next step.

On the 2007 Acura TL’s 235/45R17 size, BFGoodrich and Nitto both fit 7.5 to 9.0 inch rims, with BFGoodrich products weighing 25 pounds and the Nitto NT555 G2 at 25.57 pounds. On the 235/40R18 size, BFGoodrich and Nitto both fit 8.0 to 9.5 inch rims, with BFGoodrich products ranging from 25.4 to 26 pounds and the Nitto at 25.57 pounds. The 18-inch BFGoodrich range also includes a Y-rated option, while the others in that size are W-rated.

In practical terms, the key differences are the exact product family, small weight differences, and whether you want the added speed-rating ceiling available in one 18-inch BFGoodrich option. None of that changes the need to stay with the correct TL wheel diameter first. Once size is confirmed, compare the individual tire’s intended character and specifications rather than assuming every tire in the same size behaves the same way.

Among the covered 2007 Acura sizes, 235/45R17 fits rims from 7.5 to 9.0 inches wide, 235/40R18 fits rims from 8.0 to 9.5 inches wide, and 215/50R17 fits rims from 6.0 to 7.5 inches wide. Those ranges are specific to each tire size and should not be transferred from one size to another, even when two sizes share the same 17-inch rim diameter.

Rim width matters because it affects how the tire sits on the wheel, how the contact patch is shaped, and whether the tire remains within the manufacturer’s intended fitment range. If your 2007 Acura still has its original wheels, this is usually straightforward once the correct size is confirmed. If it has aftermarket wheels, measure or verify wheel width before choosing a tire, especially on the TL where 17-inch and 18-inch setups both appear.

No, the original wheels for 2007 Acura models are not universal across all sizes. The TL alone spans both 17-inch and 18-inch wheel fitments, the TSX uses a 17-inch fitment, and the RL includes both a 17-inch inch-based size and a metric 460-millimeter wheel size. A tire must match the exact wheel diameter it was designed for.

That means a 17-inch tire cannot be mounted on an 18-inch wheel, and a metric 460-millimeter tire cannot be mounted on a conventional 17-inch wheel. If you are working with an RL, inspect the wheel carefully because the metric fitment is the least familiar to many buyers today. Matching diameter first, then checking wheel width against the tire’s approved range, is the safest way to avoid a fitment mistake.

A 2007 Acura should be stored in a cool, dry, dark place with the tires kept away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment. Inflate the tires to a normal operating pressure before storage, keep the car on a clean surface, and move it periodically if possible so one section of the tread does not carry the load for months at a time.

Modern radial tires generally tolerate storage better than older bias-ply designs, but they still age from time, heat, and environmental exposure. If the car will sit for an extended period, occasional rolling or support stands can help reduce flat spotting and sidewall stress. When the Acura comes out of storage, inspect all four tires and the spare before driving, rather than assuming low mileage means the tires are still fresh.

On a 2007 Acura, tire life is usually judged more by age than by mileage, especially on enthusiast-owned or low-use cars. A good rule is to begin evaluating them closely once they reach about five to seven years of age, with replacement becoming a serious consideration as they approach ten years regardless of remaining tread. The DOT date code on the sidewall is the starting point for that timeline.

A car that sees occasional weekend use can still age out its tires long before the tread wears down. Heat cycles, indoor-outdoor storage changes, underinflation, and long idle periods all affect how a tire ages. If your 2007 Acura feels stable and the tread looks good, that is encouraging, but age should still be part of the decision. A fresh set of correctly sized tires often transforms how a preserved sedan drives.

Tires on a 2007 Acura should be inspected before every drive and given a more careful once-over before any extended highway trip. Look for sidewall cracking, cuts, bulges, uneven tread wear, punctures, and signs of pressure loss. Because these are modern radial fitments, pressure retention, shoulder wear, and any vibration that develops at speed are especially worth monitoring.

Frequent inspection matters because a collector or hobby car often spends long stretches parked and then returns to service suddenly. A tire that looked acceptable several months earlier may have lost pressure, picked up weather cracking, or developed a problem that only shows up once the car is moving. Make tire inspection part of the same routine as checking fluids, brakes, and lights before taking a 2007 Acura out for a longer run.

Yes, the supported 2007 Acura tires are modern radial designs, and the covered products carry speed ratings appropriate for normal highway use. The 235/45R17 and 215/50R17 products shown are W-rated, which corresponds to a 168 mph ceiling in standard speed-rating convention, while 235/40R18 appears in both W-rated and Y-rated forms, with Y indicating a 186-plus mph ceiling. Those ratings far exceed ordinary U.S. highway speeds.

Real-world safety on a 2007 Acura depends on more than the speed symbol on the sidewall. Tire age, inflation, alignment, suspension condition, and brake condition all matter, especially on a car that may sit between drives. If the tires are fresh, correctly inflated, and in sound condition, the available radial fitments are entirely appropriate for regular road use within sane speeds and the car’s overall mechanical condition.

The tire itself may show a maximum load and pressure figure, but that is not automatically the pressure you should run on a 2007 Acura in service. Among the covered sizes, 235/45R17 products show up to 1,609 pounds at 50 to 51 psi, 235/40R18 products show up to 1,521 pounds at 50 psi and 1,356 pounds at 51 psi depending on the tire, and 215/50R17 products show up to 1,521 pounds at 50 psi. Those numbers describe the tire’s capability, not the car’s recommended everyday setting.

For actual inflation pressure, use the Acura factory recommendation for your exact model and wheel package as the baseline, then confirm that the tire you choose is being used within its approved range. Pressures should never be copied from one Acura model or tire size to another just because the vehicles seem similar. If your car has aftermarket wheels or a non-original setup, verify the application carefully before settling on final pressures.

Before a longer drive in a 2007 Acura, inspect each tire for cracking, cuts, bulges, punctures, uneven wear, and proper inflation, then check the spare as well. Pay close attention to the sidewalls and tread shoulders, since those areas often reveal age, underinflation, or alignment issues first. If the car has been stored, drive a short distance locally before committing to a longer trip so you can feel for vibration or flat spotting.

That tire check should be one part of a broader pre-drive inspection on a modern older car. Brakes, fluid levels, battery condition, belts, hoses, and lights deserve the same attention, because a long trip puts every system under steadier load than local use. For the tire portion specifically, confirm that the actual size on the car matches the wheel diameter and model fitment you expect. That simple step prevents many avoidable problems.
