Im looking to run a more stretched set up than I currently have. My current set up is right on with factory specs and I would like to maintain close to the same overall diameter. Based on the tire calculator a 215/35-20=245/30-20 on a 9x20 and a 245/30-20=285/25-20 0n a 10.5x20 are these too much of a stretch. I would assume I am going to lose side wall height with the stretch so would a 225/35 on a 9 and a 255/30 on a 10.5 be more appropriate????

have 225/35/20 on 20x9 and 255/30/20 on 20x10.5 nankang tires. Stretch is ok. I just 235/35/20 on 10.5 it look great

 

I'm running 235/30 on my 9 inch wide fronts, and next i'm going to a 225/30 or 225/35, depending on availability. and probably just a 245/30 on the 10's in the back

 

I ended up running a 9/225/30 &10.5/245/30 I love the look just scares the **** out of me everytime o dodge a pothole or hit a bridge buckle lol

 

do u got pics?? i would like to see the fitment

I would do 225/35 fronts and 235/35 rears. you can do F 225/30 and R235/30 but you might can damage your wheels easier with potholes.

 

Been on 225/30 and 245/30 for months and put about 7k on them with no issues. Gone on several trips and drive through the city regularly, rims and tires are golden!!

 

I'm running 225/35 front (9.5) and 235/35 rear (10.5), has a serious stretch and enough sidewall to protect
