Got new tyres for the back of my chaser last week and one of them started rubbing.they are the same profile as the last tires so im a little confused to how they never rubbed before.Ive been told an aftermarket sway bar would solve the problem.anyone got any ideas on what to do???
Is it a different brand of tyre? Sometimes the "shoulder" of the tyre can be different even if the profile is the same. It might not tuck in as much.
Sorry that's not a great explaination of what i mean:o
ya its a different brand...the old ones were toyo proxes and the new ones were federals....ya i get what u mean...u think that could be it?
You could camber it a bit more but unfortunately when you modify you get these probs. More camber = less tyre wear. Are the arches rolled. ?Quote:

What he said ^^^^^^. The same thing happened to me when I got new tyres on 10j wheels, but it was just an excuse to burn some thread off. :)
What size are the tyres? I think it was 255/40's that caused rubbing on the rear of my car and the arches were rolled.

The more negative camber you are running the faster the inside of the tyres will wear especially in road use.
Well i had the opposite happen, i changed to toyos and had more space.Quote:

Would it be fair to say that toe in/out causes more wear?Quote:

I haven't put many miles on them yet though so it's kinda hard to tell.
i was only sayn to meself the same thing ????? maybe im wrong ?Quote:

Oh,No,Wait,Wrong forum:D
I found the same on my cossie when I fitted Federals, they began to rub. It seems that Federals are just that bit wider then other brands, however personally I prefer the tyre to be slightly wider, gives a bit of extra protection to the alloy.Quote:

The inside 1-2 inches of the tyre then wear down to the wire while the rest of the tyre has a couple hundred more miles in them. This is due to the toe and not camber (rubbish 11° rear beam design!)Quote:

That's my 2 cents anyways:)
Not always the case. I worked in garage that did tracking and heard from other garages that x5's were one of the biggest offenders in tyre wear and very hard to be got right. The screen would be shown up green that all parameters were correct but they would still be ateing the tyres off. One garage even has an offer where if you buy a set of new tyres for an x5 from them they will track the car for free and do it for half price any time you want until the tyres wear off.Quote:

Right, a lad I know has one and I've never heard him complain about the tyre wear, but that's not saying it doesn't happen.
X5 is a bad example so. :((I'll get my coat!!!)
Is he running the Poverty spec 17's,If so he'll get away with it,Maybe!
Any upgrade or decent spec OEM bigger rim will create inner tyre wear!
Camber does have a negative effect on tyre wear, how much depends on how much the camber is off of course, but also consider that when the camber changes, the toe is also effected on certain suspension types.
Toe will cause most wear to tyres though.
And also bmws with big wheels are the worst examples. x5's, 5 srs and 3 srs with larger optional alloys will nearly always eat the inside the rear tyres due to the factory camber setting.
Great minds and all that Jazz:rolleyes:Quote:

285/45/19 Rear and 255/50/19 Front is the large alloys on x5's
Most of the 06 on upgrade spec came with 20's,315/35/20!
Ates the inside of the tyre and serious road noise,Ive tried Micheys,Toyos,B/Stones and Contis and the best results yets are toyos,Buying them at the mo for about 160+vat
Sierra suspension for example, the toe and camber changes as the suspension compresses which is why some people pay a grand sterling for a 6° adjustable beam to stop this happening.Quote:

Adjusting camber on your car, in cases would affect the toe, but this might not always be adjustable. The tyre starts to eat itself and because "it was only the camber adjusted" people assume, this is the root cause.
Shoot me a PM next time ya want them €160+ = €193.60, I can get them for ya for €180 all in.Quote:
