HI everyone i need some advice on which tire size i should go with. Im lowered on Bcr coils and im putting on 20x9 +32 and 20x10.5 +45r. My question is can I use this tire set up 245/30/20F and 285/25/20R and will that size keep it close to factory specs. Thanks

 

Run 245-30-20 and 275-30-20. Your good to go. 285 25 20 is very thin , unless your going to slam the car.

 

Assuming you have the F-Sport, the f sport rears are 26.30" tall and 275/30/20 would be 26.50" tall so that would be perfect. A 285/25/20 would be slightly shorter than stock.

 

I have received the advice to go with 245/35/20 and 275/30/20 tires, but this is in combintation with the RSR springs.

 

I do have the F-sport. But wouldnt the 275/30/20 have the stretched look? Cause I dont like the stretched look. Im lowered down to one finger gap and dont want to roll my fenders. I had that same set up on my 11 GS and lowered the same with no problems.

 

My 275/30/20s have a slight stretched look, while my 245/35/20s are more 'square'. That said, my fronts do rub slightly (tanabe nf210 drop) whereas the rears do not.

 

It might. It depends on the tire. Some brands run big and some run small. It would be nice if your tire shop would let you test fit the 275 but some shops consider the the tire sold once it's mounted.
