Dunlop Sportmaxx 295's in front!!!!!

[jigaro]

Hello,

I have style 215's

My tires where extremely worn, and i went to a second hand shop, where they import used and new tires from Germany.

They gave me 2 tires for the back 325's Dunlop sportmaxx, just like i had before.

But for the FRONT they installed Dunlop sportmaxx 295's, they said they took it off from CAYENNE which crashed in Germany.

I went and did alingment, and everything seems to be fine.

I'm just wondering what do you guys think about 295's in front?

Any experience?

First off are they 35 or 40 series profile and have you done a calculation on the rolling diameters compared to your back tires.

Second, I would make sure that the 295's are load rated for the BMW. The Cayenne is a heavy beast so I would assume that they would be.

Third, are you getting any rubbing?

They are 35, the same ones that i have on the back!

Not sure about your second question, but i assume if they can handle cayenne they can handle X as well.

What do you mean by rubbing?

When I say load I am talking about the weight that the tire can handel. That being vehicle weight and the stress when say cornering at 35mph. If the tire is not rated high enough for your vehicle then it could fail. Looks like it has a 107 rating which matches OEM numbers

When you have the steering wheel completely on lock(cranked all the way) are you rubbing your fenders on the inside?

Thanks for all the input you are providing.

I think it has exact same numbers as the Dunlops that i had before, so it should be fine, i guess if it was on Turbo S then it should not have problems with my X.

I just turned the wheel all the way in both directions and it does not rub, i will check again tomorrow.

How is it in general, if you have wider tires in front does the car corner/handle better? Is it stickier or not? In other words, will it handle better now, that i have 295's in front, instead of 285's before that?

Just like i sayd in the very first post, they where take from Porsche, and when i checked on tyre rack, it seems to be AUDI aproved.

It does not say anything about runflats, and thats why i think the ride seems to be softer.

What do you guys think? I'm going again tomorrow to sort this thing out.

The more stagger you have in your tires, usually results in more understeer when cornering(which is pretty common in modern BMW's). The less staggered in your tires, the more neutral your car will turn. You may have helped out your handling.
