Can I run 275/40/18 on the rears and 245/40/18 on the fronts on the OEM18 inch rims?

 

Can they physically fit? Maybe if you find a shop stupid enough to mount them. Should you mount those tire sizes? IMO no, not at all. the 18" wheels are only 8" wide, and should have no wider than a 245 mounted on them. A 275 requires a wheel at least 9" wide. You could go with 245/40/18F and 245/45/28R

 

+1... This is what I run and I love it.

 

o i thought you werer running 28" rims rear LOL well the reason i ask is i am selling these tires and another guy wants to buy them but has 18" oems.. so maybe ill sell him the fronts?

 

can someone post some pics of some 275s on the OEM 18s plz!?

 

Tried a quick search and couldn't find anything for ya... I did see a 275 mounted on an OEM 19 but that's 8.5, and even THAT'S pushing it... I wouldn't recommend it.

err okay

 

If it makes you feel any better, I was running 255/40's on my OEMs for a while and they worked out just fine for me..

 

lol i just want to sell my tires and i want to know whether i can sell them all to one guy or need to split them up

 

I would not with a good conscience sell those to someone to mount on OEM wheels

 

yea... 275's on the oem 18's arent good.. i actually did it.. and i just didnt have that piece of mind the whole time.. didn't feel safe.. it was ok in a straight line.. but when i was on a turn or off ramp or on ramp.. just felt like i was gonna break loose and hit the wall.. i had no real control of the car when it came to turning so i took them off and went with some 245/40's in the front and 245/45's in the rear.. good luck

 

curious, did you guys do anything else to fit the 245/40 and 245/45 combo's on your OEM 18's? I have a stock G Coupe and I wanna do this as well, but wanna make sure that everything will be ok if I do...

Also, is there any benefit with going with this setup or is it just for looks?
