The PSSs are a great decision. I will be going with those again when it's time to replace mine. I will probably go with 245s also, but not sure how much, if any difference at all, it will make, but given that I'm traction limited in the first couple gears right now I'm willing to experiment and go up a size. Anything more than that would be overkill, you won't necessarily get any more rubber on the road, you're just going to end up with tires that have to "bunch" somewhat to make them fit, which you don't want.Thanks guys. I'm running my stock Perelli all seasons right now on stock wheels... gonna throw my Dunlops back on in the spring and when they wear out I think I'm gonna splurge in some Michelin PSS. What the perk in having a 245 or 255 as opposed to 235? Thinking about going 245/40r18 next time round.
More pressure leads to a smaller contact patch on the tire. So less of the tire is touching the road. That being said, you can see slightly better gas mileage because you are reducing the rolling resistance of the tire due to many different factors, but basically because you have less tire contact.Whats the benefit of having higher pressure? I dont know anything about tires... trying to learn.
