I'm considering to pick up these wheels - Wedssport SA55M Matte Grey Machined 18x9+20.

Michelin PSS are the tires of my choice. What size should be the best fit for these wheels? I would like to go 265/35, but wondering whether it would be too flush. I don't want to sacrifice handling by going wider.

Also how much of a noticeable difference would be between 265 vs 255 tires? Considering these two scenarios: DD and Auto-X?

245/255 fit well on a 9" rim, 265 is too big.

I agree, that how it is in general. But I'm actually looking for someone who actually run the setup to better assist me in my decision. Is 255 flush for this setup?

I believe tkromer is right with the tire size being 245. I never ran this set up and I know a lot of people usually get the 18x10 sa55m. However if the stock tire is 245 on an 8.5" rim and most people run 265 on a 9.5 rim, 255 is perfect for a 9 rim. But the michelin PSS run wide in width. So 245 would fit well

That answers the question. Since AWDs can't go wider than 245s in street-tire classes, you put 245s on the car, eh? And before you say that 9"-wide wheels are wasted on 245s, check to see how wide the wheels are on the Evos and Scoobys that have trophied in STU at Nationals for the last 5 years.

265 will be flush, 255 small stretch. These tires run a little small. I run 275 on a 10" rim and there is a slight stretch.

I'm not looking tires to win auto-x trophies. To be clear, my car is DD and would do occasional Auto-X. I'm yet to attend even a single auto-x event and yet to learn about their classes.

Anything wider than 245 is too much for Auto-x, is that what you are saying?

BTW, my car is already modded, so the stock class is ruled out.

Disagree. They run wide in 265. On my 9.5 inch wheel the Tire is not flush but bulges slightly. OP on my 18x9 Advans a 255 that ran big (I had z1*) fit perfectly flush if that helps.

I was saying that AWD cars are limited to 245s in street-tire classes, not that more tire wouldn't be better.

Cars in the Stock class (note caps) run R-compounds. You are allowed many mods in the street-tire classes.

But let's drop the whole thing, since you don't seem to care.

for accurate, technical info. 265/35/18 PSSs are some of the widest 265s on the market.

The 255's on my 9.5 are wide too. PSS's are VERY wide across the board.

EVO LVED

I can't speak to 265, but I have run both 285 and 275 PSS on my car. 285 was flush, 275 stretch on 10" wheel. Every other 275 tire I've seen on a 10" wheel has been flush. So again, PSS runs narrow.

But you can look it up.

For example, the sponsor of this forum has a great website, providing such things as the tread-width (in addition to section width) for all tires that they sell. From their site (see, e.g., http://www.tirerack.com/tires/tires....um=635YR8PSSXL ), you can learn that the 265/35/18 PSS is 10.1" wide at the tread, even though the 275/35/18 PSS is only 10" wide at the tread. This is what Hikaru seemed to know and told/reminded us. And that's the kind of thing I would love to see more of, rather than the assumption, for example, that the 265 of some specific tire must be less width than the 275.

That's interesting. Does that mean PSS 275s will have less contact patch than 265s ?

I run 245's on an 8.5in rim. They would definitely work for 9. they Are a very wide tire.
