I have the SF Challenges and need to know would 295 30 19's or 295 35 19's fit? Thanx

 

are you lowered? what size rim too, that matters alot.

my 8.5 +10 barely fit 255. lowered on eibach prokits.

When determining whatll fit and what wont you just have to break down the offset, rim width locations.

take a 10 inch rim + 0 offset. 5 inches go to the left of the hub and 5 go to the right. Lets say its a passenger side rim. Now if you increase the offset to 23 mm (close to a inch) Youll now have 6 inch to the left of the hub and 4 to the right. a 295 tire is about 11 inches. Since the tire is centered on the rim, youll have 6.5 inches to the right and 4.5 to the left.

so, convert my 8.5 +10. I have roughly 4.5 inches to the left of rim, and 5 inches of tire to the left. 4 inches to the right of rim and 4.5 inches to the right of tire.

Now you also have to look at sidewall height. My 255 have 4.5 inches of sidewall, with a over all diameter of 27 inches.

295/35/19 has a 4 inch sidewall and overall 27 inch diamter.
295/30/19 has a 3.5 inch sidewall and overall 26 inch diamter.

 

Sorry about that. They are 19x9.5 and 19x10.5

 

I do have coilovers

 

ok, 10.5 + 23:

means you have 5.75in to the inside, and 4.75 to the outside. Your tire will be close to 5 inches to the outside and 6 to the inside. Sounds like itll be close.

Id go with a 295/30 and seek some help from people with the similar setup. the coil overs will help.

someone double check me.

 

Thanx. I know someone with 295's on his G35 and they fit without a problem. I dont know if he went with 30' or 35's though

 

You will have to roll the fenders for sure.
