255s on 20" x 9.5" wheels on a Performance 3

The tire guy I go to, thinks the 255s on the front would be better than 245s, which I see everyone else using.

Does anyone know if 255/35/20 will have any rubbing issues on a Performance 3?

Thanks

(I searched for the answer, but didn't see anything)

Tire Size Comparison

Use this to get an estimate of overall diameter and wight tire. On my P3+ I’ve 255/40/19 which has the same diameter as 255/35/20 you are looking at. It will rub with stock wheel, but it could be mitigated with 3mm wheel spacer.

Attached is a photo of rubbing on upper control arm.

I believe the stock 19s are et40 and the stock 20s are et35 so 255/35/20 would probably be fine.

I have 255s on the front and 285s on the rears. No rubbing and they look great. They really fill the wheel well, without lowering.

I have 20x9.5 et35 with 265/30/20 on P3D+ and there is 5-6mm from the knuckle. 255/35/20 is 27” diameter vs 26.2” for the 265/30/20. Depends on the offset of the wheel for the 255/35/20 to not rub. I also have 255/35/20 on 20x9 et30 and that doesn’t rub.

Pics below of the 265 tire.

Hey guys, I'm trying to research if I could fit 265/30/20 on 20x9 et38 wheels on a lowered P3D+. I currently have 245/35/20 on with no issues. I understand the diameter of the tire would be smaller, but I was wondering if the width of the tire might rub on the upper control arm. Appreciate any helpful input. Thanks.

I have a 265 / 30 Michelin Pilot Sport 4S on 9.5 inch wheels with 40 mm offset but also with aftermarket rotors effectively rendering them a 35 mm offset wheel on my car relative to yours (meaning that your setup if you have the performance brakes with the thin rotor hat is effectively 3 mm more inboard than mine). The changed configuration you are proposing will not rub on the overhanging portion of the control arm, but the 265/30 is going to move the sidewall laterally roughly a centimeter out on both sides. You can get a precise figure by getting section widths (not tread widths!) for both your current and your new tire and simply subtracting. If you got 11 mm of space between the current tire wall and the control arm laterally, with your current 245 / 35, you should accommodate the wider Tire. But it's going to be tight because with my setup and effectively 3 mm a more outboard wheel compared to yours, I have about 4 mm between the side wall and the control arm. So it's going to be tight. Take a 1 centimeter wide object and see if you can comfortably fit it between the sidewall and the control arm. If you can you'll be okay.

I reached out to the Mad Hungarian to get confirmation before I went ahead with this and did some rough calculations of my own and they proved to be pretty accurate. If it turns out that the 265 will not clear you do have the option of getting aftermarket rotors like those from Mountain Pass or Racing brake both of which have a 5 mm a thicker top hat. Not cheap but it will fix the problem because it will move the wheel 5 mm outboard.

If you're getting the 265 / 30 Michelin Pilot Sport 4S, you will not be disappointed. It seriously upgrades turn in and traction at the front.

Thanks dfwatt for the very informative response. It seems I can squeeze a 12mm thick eraser in the gap. It would definitely be a tight fit with my current setup. I previously was looking into upgrading my brakes, and now that you pointed out the fact that aftermarket rotors increase the wheel space I so desperately need, I will definitely seriously consider doing so. Thanks!

You really only need about 2 mm clearance. I wouldn't cut it any finer than that but I think you got just enough to fit the 265/30 s, but for sure the aftermarket rotors would remove any question about borderline clearance. What tires are you thinking about getting?

Most likely PS4S, was also thinking about cup 2s.

Sorry to hijack your thread but I’m planning on going with 20x9” +35 offset. Could I do 245/35/20 all around or would 245/40/20 all around work? Which is more comfortable of a ride?

A 245 / 40 - 20 will not fit on the front due to its fully one inch increase in diameter. It will contact the upper part of the front control arm. The 245 / 35 is about a 1% increase in Rolling diameter and can be accommodated however.

How about with the new P3 Uberturbines? They are 20x9 +34. I know I can run 245/35/20 as that’s what the track pack comes with but what about 255/35/20. I want to purchase some Pilot Sport AS4 since the temp has been dropping to the 20’s lately.

I'm running 245/35 20 Cup2s on 20x9 +34 aftermarket rims. Before that I was using 265/35 19 Cup2s on 19 x 9 rims. The 20" combo is faster, although they are the new 'Cup2.5' Connects, which are supposed to be better in any case.

Are you going to be tracking the car? If so then the Cup 2, particularly the more recent Cup 2.5 Connect is better choice but if you're driving on the street it's no contest the PS4 is is the best street Tire available. Another question might be how much you going to be driving in the rain. The Cup 2s are kind of treacherous frankly in wet weather, PS4s on the other hand are one of the best rain tires out there
