Im due for the some rear meats and was thinking of going with a 285 vs the 275 im running now. I have MRR gt-1's and im not sure of the offset but i bought them from the vendor here and they are sedan fitment. If i plan on lowering in the future, would it be adviseable to go with a 285/30 in back? I dont want something thats going to rub

 

285 is pushing it.
Especially on MRRs.

Maybe if you go 285\25 it might work

 

Not sure what the offset on the MRR is, but if it's around a +40 to +50 offset, 285-30-20 will work. Terry's running 285s on a 20x10 +48 with corrected camber and there seems to be some more space available to push the rims/tires even flusher to the fender. There's also a 1st gen sedan running 295s on a 20x10.5 +54 offset rim.

The rolling diameter of a 285-30-20 actually matches the stock diameter better than a 275-30-20.

Stock 245-45-18s = 26.68"
275-30-20 = 26.49"
285-30-20 = 26.73"

 

Yeah you can run 285s all day long,you can even run a 285 35.

 

Piece of cake if the offset sand camber are correct. Here are pics with PS2s which have a more "square" edge between face and tread and T1Rs which have a slightly "rounded" edge. Both are exactly flush to the stock fender. These were taken with the camber at nominal setting within factory spec.

Sweet! thanks guys. 285/30's are actually cheaper than then 275/30's haha.

 

Terry - do you notice a big handling difference btw the T1Rs vs. the PS2s? Seems like every supercar that has amazing grip comes stock w/ PS2s. But they're super-expensive compared to the T1Rs.

 

PS2's are one of the best performing street tires ever made and they still live up to their name. That's why they're more expensive than T1R's.. Toyo, Falken, Kumho... they're all tuner brands and you'd never find them as factory equipment on a vehicle.
-GP-

 

+1. I originally wanted PS2, but decided I didn't want to spend the $$ on tires. There are a lot of good things said about Falken 452, but the 285 were on back order when I needed them, so I went with my third option, the Toyo T1R.

AlterZgo: Sorry, no comparisons. I only borrowed the backs and put them on my new wheels for fit testing at the time.

 

I've got the Falkens on the 3 and they're a great tire for the price. I also had Kumho SPTs on my last car and, for the price, they're very hard to beat

 

Is it true that the Kumhos flat spot easily if they're not driven daily? I drive my G about once a week now and I'm looking for a tire that maintains it's shape well.

 

I've never read about that complaint, but my car was driven daily so I didn't experience that.
