I guess I really should have checked into it before I went that way though,

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

I have the bfg ta kd 285's rear and running the junk p zero's front which can't hang with the stickiness of the bfg's. In any event I have 8.5f and am deciding whether to get 245's v. 225's for the front. they are both 40 series. As porsche likes to keep the tire size @ 25.1 it would bump the overall size to 25.7. Is this that big of a deal? I was warned about the size etc. It is worthwhile to note that the footprint of the 245 v. 225 is significant @ 8.86@ a 225, and 9.65 for the 245. any thoughts? I was really gung ho about getting the 245's but I don't want to do anything that will not only cost money but be unhappy with later. Suggestions?

POST 2 / ORIGINAL POSTEROriginal post

Other than the theory behind the ratios etc. can anyone tell me of their real experience adversly or beneficial towards that end? thanks.

POST 3Original post

Sean - What about the 235/40's - this is the standard size for GT3 with 8.5" rims? I would say that 245/40 are a bit too tall. Are there any 245/35 available? Having more than a 5% difference in rolling circumference between f&r can cause problems for the PSM (which you don't have on a 99) and possibly the ABS (which you do have). Also, the taller sidewall will raise the front of the car slightly (bad for aero lift) and give you less precise turn-in. But to answer your original post: no, I have no direct experience with the wider/taller fronts...

POST 4Original post

Here are the tires available in 245/35: http://www.tirerack.com/tires/Compar...ark=1&x=17&y=4

POST 5Original post

Oops, looks like the 245/35's are too short in the P Zeros anyways - I'd go with the 235/40's myself...

POST 6Original post

Sean, Porsche has done the research for you. I'd stick with stock tire sizes.

POST 7 / ORIGINAL POSTEROriginal post

yeah I hear you I think I will just do 225's I really really wanted bigger but I want to have the same tires f&R and bfg only makes 245/40 and 225/40 no 245/35!!! Those bastards!!!

POST 8Original post

I think most of us like the look of wide, low profile tires. I think you made the right choice of performance over appearance. I'd hat to mess up the one thing that make the 996 so fun and that's its handling.

POST 9 / ORIGINAL POSTEROriginal post

well if those bfg bastards made the correct sidewall height then I wouldn't have an issue. I guess I really should have checked into it before I went that way though,
