Causes Of Front Tire Wear On Inside


Recommended Posts

2000 Boxster S, 47k miles, 10k miles on front PS2's. Just got back from a 4000 mile road trip and was noticing more tire noise than usual. Checked wear and find rears have 7mm inside to outside (even wear, these were new tires just before the road trip). Fronts, though, have 6mm on the outside, 3mm on the inside. (Front tires were not replaced when new rears were put on.) Both fronts have the same wear pattern. Is this just camber or is there something else? Running 30lbs in the fronts.

Thanks, Jim

Alignment toe adjustment -- find a really good Porsche alignment shop, may be dealer, may be not...

Over 20 years ago I found a very old guy in Kentucky who told me he could align a wheelbarrow - so I gave him a chance and he did a great job on a '72 991T

...sometimes you need to talk to a lot of different people to find the right tech for the particular job...

Let me add one followup item. I did not notice abnormal wear on my front tires prior to the 4000 mile road trip (I checked the tread depth and it was about 7mm). For the trip the car was "full", ie, front and rear storage areas were packed full (but mostly just camping gear), plus I had a passenger for the whole trip (both of us weigh about 170lbs). I'm wondering if the extra weight might have caused uneven front tire wear.

Thanks for all your responses, BTW.

Jim
