Will this tire size fit my 07 2dr LT.. I have aftermarket wheels just need new tires...

245/40/18ZR

 

specs on wheels?

 

little big. doubt that it will fit. Biggest I've seen was 235

 

ive been wondering the same question

i am going to get some rims soon but i want to make use of my 4 tires in the garage

 

I need a more firm ride... I have 215/35/r18s now on it and its a rough ride.... I know they say a 40 will fit but not so sure on the 245 rating....I need the largest tire I can get to free up some of this nasty wheel gap. I got a bodykit I just fitted the other day and with the kit on it there is no room for the lowering springs I have in the garage. The car will be sittin like 3 inches off the ground at stock level. If I throw the springs on I'll be makin ants duck all the time. Not cool.

 

Stick with 40's the smaller the number the thinner the tire. This website helps too

you can only go 235 even then that is pretty wide tire for our cars

ok well since his problem is kinda solved

can i fit a 245/40/18 with no rub?

 

Stock Tire - 245/40R18
Section Width: 9.64 in 245 mm
Rim Diameter: 18 in 457.2 mm
Rim Width Range: 8 - 9.5 in
Overall Diameter: 25.71 in 653.03 mm
Sidewall Height: 3.85 in 97.79 mm
Radius: 12.85 in 326.39 mm
Circumference: 80.77 in 2051.5 mm
Revs per Mile: 809.0

You will need a 18x9.5 to fit 245 and above.
On my car i have 18x7.5

 

so i take this as a yes?

 

no rub. but the tire might stick out of the fender

 

245 will definetly stick out of the fender with aftermarket rims....the nicest flush tire ive seen with afermarket rims is 225 40 18
