In that case is there a certain wheel and tire weight that you should try and stay under. And you mean the added grip allowing you to corner much harder puts tons of stress on the wheels bearings and what joints get stressed?

probably not. The major load is due to the GRIP, not the extra 5 or 10 lbs the 315s may add over your current wheel/tire.


Most guys I know that race ITE replace the hub at LEAST once a year... although any serious "track incidents" may require one as well. Hubs are like gold if you can find them cheap.

That said, my daily driver (with all-season 245's up front) has 130,000 miles on the factory hubs. Under normal street duty they are very dependable.

Shoot, its better than 4MPG race cars that barely make that, what I meant was daily driver MPG if your car is a driver.

Yep, think about it for a second. The bearing is whats between your (sprung) car weight and the ground essentially, so if you put more load on it in any form, it will wear faster.

true but if you drive on the street i don't think you would see the kinda loads you would see on a track, so wouldn't the hubs last longer?

Sure, they should last longer than racing, that is another obvious "most likely" scenario.

But, why build a race car with 315s on all four corners, and only drive it to work? If you can afford it then I suppose I can understand that, but the economy of the idea just doesn't suit me.

Last longer on the street vs track ... certainly

Last longer with 275s vs 315s ... certainly, even on the street.

315s on the front is not street friendly by any stretch of the imagination. It road hunts terribly. And that alone tells me it's harder on bearings, ball joints and rod ends.

Maybe with alignment.

But that is a HUGE contact patch to deal with

Hunting is a fact of life with all wide tires. You can reduce it some by reducing the caster, but that has other effects too.

tracking with my 275s are interesting to say the least, I can imagine it would be a task with 315s. not sure I could do it.


So where's those pics?
