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

My rear tires on my 2001 c4 cab just do not seem to fit over the wheel enough. There is absolutely no protection for the rim. I wanted to put bigger tires on the rear, maybe 295. I have the sport rad wheels in 18 inch size. My problem is, is that the dealer told me that a different tire size will screw up the AWD system and ABS or something. Is this true? What is the biggest tires I can fit on my wheels in the front and rear? I am was thinking of going with SO3's instead of the Pirelli becuase I am getting a little less than 7k miles on the rear tires. Both outer edges are wearing to almost bald and the middle is not. The dealer said it is normal, but I do not know if I believe them. What do you think?
