Tire size for 8.75
 

Just purchased some xxxr 527 18x8.75 what size tires should I buy? Was thinking 235/40/18 all the way around or 235/40/18 in front and 245/40/18 in the rear ?

Why don't you use a tire size calculator?
Why don't you search?
Why don't you look in the xxr thread?
225/40-18

225/40 or 245/35 is the closest to stock sizing, which will keep the speedo error minimal. I went with 245/35 and I love them. I would try to stay as close to those sizes as possible, but that's just my opinion.

Thanks I pirchased some nitto neo gen 225/40/18
