does anyone know the biggest tire fitment i can fit on the 19'' oem rays ? right now im running 225f 235r but i wanna go like 245 f 255 rear but i don't know if they'll fit on my oems.

No problem you can run 245s (F) and 255s (R) without issues and you'll enjoy how the 245s make your front end more stable at speed. Never understood why Nissan likes running those 225 on the front?

I ran 275s on the rear so you're good.

+1 on 245/255
You might get away with 265 but personally I wouldn't go bigger then 255, especially if you drive your car hard.

I'm curious how those 235's look on the rear. Most 245's look anorexic, can't see how 235's look good

No one mentioned 235s, they're not even large enough to add the needed stability to the front....

OP said he's running 235r.

thanks for the replies guys ! now i can go run bigger tires and not be so skeptical :P and yes i am running 235's in the rear and YES they look silly LOL, i wanna run bigger tires so i can get more stability when i take my car to buttonwillow for my first track event !

+1 245 in front. 245,255,265,275 all fit the rear. Just a matter of choice. 265 and 275 may consider 35 series to closely match original diameter.

You NEED a 35 series sidewall if you go over 255. Or else you're only going to increase tire roll aka make the cornering squishy. If that's what you want, you need to give up on track events.

I do not recommend anything larger than a 265/35 fro the rear.

glad i found this thread. what is the widest tire i can fit on the front and rear on the OEM 18s?

I wouldn't even go over 245 to be honest. They're only 8" wide.

I would say 100% maximum is a 255/40. But personally I wouldn't run that.

that's true, it is only 8". I'm just used to running wide tires on my s14- 235f/265r. might as well just stay with the stock fitment. thanks for the info!

Pick up some coupe 19s and slap some 255/35 or 265/35 on em.

so those clear the brembos?
