These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Has anyone successfully fitted 235-40/18 and 275-35/18 tires on the standard 2000 18" rims? The reason I ask is the specific model tires I'm looking at are new and not yet available at the 265-35/18 size but 275-25/18 is listed, so I thought to go up 10mm both front and back at the same time to get a bit more contact surface area. TIA.

I have 235-40/18's on my 18 x 7.5" front rims. Look good, slight sidewall bulge. I have 265-35/18 on the rear 18 x 10" but many recommend wider, 285 even 295. I will definitely go wider (285) in the rears when the time comes.

POST 3Original post

Go to go 265 on the rear otherwise aspect ratio will be off. 275 will be too tall.

POST 5Original post

just put 235/40, 285/35 MPSS on my 2001 C2...recommended from my indy....fitment is fine, no rubbing, speedo does read dead-on accurate now...

POST 6Original post

2004 40th AE 235/40 - 18 & 295/30 - 18 with no rubbing on stock rims

POST 7Original post

It isn't a problem fit. 235 fits all but the most slammed cars. 275 is a good fit too. If you have an 11" back rim, a 275 minimum will be needed. Watch your OD's if AWD. Please call me if I can help.
