For sure. Thank you both very much.

 

Just an FYI for people wanting to go +42 rear:

I have 8.5's in the back with +42 offset, and I still rub with 235's.

No big deal though, a little fender rolling will take care of it..and either relocating the bumper tab or grinding a little of the washer off.

 

would 16x7 +33 offset rub at front?

 

Yes.

 

I'm looking at a set of wheels with the following offset/tire size:

18x8.5 +52 225/40/18
18x10 +58 275/35/18

My question is with a 1.5" drop will these rub? Don't plan to shave/roll fenders

 

You're right at the minimums. It could rub, depending on your alignment.

 

I am currently running the following :

Front 18 x 7.5JJ Offset +45 225/40/18 Toyo R888
Front 18 x 8.5JJ Offset +44 245/40/18 Toyo R888

I am intending to try 235/35/18 for front and 265/35/18 for rear Pilot Sport Cup. I have front 3+ degree -ve camber and rear 4+ degree. I have also rolled the rear fender somewhat. Will it still rub ?

thanks

 

I personally have no idea. All the data I compiled for this topic was based on stock cars with stock alignments, or close to stock. Maybe someone with more extreme fitment experience can chime in.

How much fender clearance do you have now? If you could measure it, you could make some calculations based on tire specs.

Cheers,
Ken

 

Thanks for helping out. I have about 5mm clearance now for both front and back, after all the camber adjustments and rolled fender at the rear.

 

If that is the case now, then you can theoretically go 10mm wider on your tires and they will begin to touch. (235 and 255.) You may also want to check the tire tread width specs for the R888 and PSC. If the PSC runs wider than the R888 for a given size, you might run into more rubbing than you expect.
