Damn, I had a nice long post and clicked paste instead of copy so I lost it. I'll sum up with your article is very correct and technical if you can follow it; it also makes no mention of caster wearing out tires.

If you are only getting 15K on 3 sets of tires you have MAJOR problems with your car....get it checked soon.

Spindle inclination is the imaginary that runs through the upper and lower ball joints perpendicular to the ground, from the side veiw.

 

Dodgemech, I think you have an evil[sm=badbadbad.gif] twin, who uses your login. You better check on it.
In my original post I briefly mentioned my attempts to correct the tire wear problem; it did cost me few hundred bucks and left me with not-centered steering wheel (annoing, if you have controls on the winglets) and firm resolution not to let any dealer touch my car again.
I also mentioned that caster affects wheel camber while turning, thus exposing the edge of the tread to MORE wear.
...Especially if you're often wondering how much faster you can go through that turn and still make it. Sinful thoughts, but I keep my R.I.P. Celica, Eclipse and another Eclipse in my best memory...

Don't get me wrong Dodgemech; I believe that there are good mechanics in some dealerships, just not in ones I ever went to. Last dealer was trying to convince me that excessive wear is due to ' bent upper control arm in the rear right'. Now, that's some appalling BS !! If you've done this kind of damage to your suspension, tire wear is last of your problems, once you're out of coma...

I fully agree with "justaocboy", that underinflated tires may have very serious outcome - first hand knowledge, I was lucky though; rear wheel - but 30-35 psi is hardly "underinflated". I used to run my tires at 45-48 psi and in my nonprofessional belief; it was responsible for increased wear. I researched it somewhat; I couldn't find any evidence that such a high pressure gives you anything but more responsive steering - I mean lifespan-wise.

QUESTION TO EVERYBODY: What pressure you keep and do you notice any impact of it on the tire wear?

Nope, it's just me and yes I am evil most of the time (but also pretty knowledgeable about anything automotive related with a pedigree in brakes and suspension).

I set most LX platform cars at 38PSI COLD. 45-48 is excessive but shouldn't wear out a set of tires in less than 15K or so.

FYI, the added camber gain provided by increased caster is minimal and will not account for excessive tire wear what-so-ever. Unless of course you drive on oval track and are constantly in a turn in which case all the edges are going wear regardless.

Name is Denny, hate being called Dodgemech...don't know why I choose that as a log-in but if I change now would confuse many.

 

TXRide you should start a new thread with a poll in it. It would be easier for users to spot the question and get some good results.

 

you're right! i'll do it.

 

OMG!! I can't believe it but i have an 05 magnum with continental tires . . . its a little over a year old and i need to replace the tires?? i realize NOW (not when i bought it though) that they are touring tires, yada yada yada .. .at 3k it was pulling to the right .. .dealership said under-inflated tires . . .at 13k still pulling to the right . . dealer said tire wear . . .reluctantly did an alignment (said it was out of warranty but since it was noted at 3k they would do it ) and that i would be lucky to get 20k out of the tires!!! wutt??? wutt??? . . now at 18k, tires are evenly worn and continental has offered a 35% discount . .im not sure, but i dont think i want to put the same kind of tires back on it .. why would I??? only tires i can find that will fit it are pirellis .. anyone know anything bout this (since im gettin the run around from continental, the dealership and chrysler)????

thanks!

 

I have the Pirellis and love them, much better ride and handling than the Contis. The Euro models that go 150 MPH come with the Pirelli 225x60x18.

 

Ive got 10,000 miles on my RT. I have slight feathering on the outsides of both front tires. Im just going to rotate them side to side to even it out. I generally dont rotate tires at all. My wheels are not swapable front to rear. Since their custom wheels with a slightly deeper offset, I attribute the unusual wear to that. My alignment is in spec, and mine tracks straight with none of the ' pulling ' stated by others. Im getting ready to swap the custom wheels now for winter back to brand new OEM wheels and see what they do over the winter. I have the Conti Touring tires on both sets of wheels.
