Tire shaving

[650GC]

Does anyone know what tire shaving is?

If yes please recommend some shops who does in Ontario, Canada.

I have Michelin PSS tires and front are new and rears are about 75% life. I would like to shave front tires to same thread as rear due to transfer case jerking while accelerating hard. Normal driving is fine but I could feel something is slipping when I floor the accelerator.

I am confirm that is it due to different thread wear since I switched the tires to factory wheels and tires and problem goes away.

I am running the right tires front and back and less than 1% of difference when NEW.


255/35/20 Michelin PSS front on 9" rim

295/30/20 Michelin PSS rear on 11" rim

You can google what it is. They turn the tire and use a blade to cut the tread. Works just like a wood lathe. I've seen pictures online. No idea who does in Ontario. Call a few shops and ask who does it.

I personally would be reluctant to do anything intentionally to compromise the integrity of a tire. Keep in mind that the contact patch is the only thing keeping 4,250 lbs in contact with the ground at any given time depending on road conditions, tire pressure, and speed. Please be careful having that tire shaved, long term and safety first, might want to invest in new tires and proper alignment. Just my 2 "sense".

Shaving a tire does nothing to the "integrity" of the tire other than cut down the tread depth. TireRack will do it when you buy new tires from them for $20 a tire. Racers always cut new tires down so you don't get excessive tread movement.

What I find interesting is that most of the xdrive cars from the 5 and 6 series range have about 1% smaller diameter tyres at the rear.

By going up 10mm width at the front and 20mm width at the rear you've actually matched the front and rear diameter, but then with your different tyre tread depths you're actually closer to stock than with new 255/35 and 295/30.

Have you tried turning DSC completely off and seeing if it does the same thing?

Yes your right, I did notice that all 6 series including m6 have close to 1% of rolling diameter difference being front 26.8 and rear 26.5. Which is about 1.12%. I did try DSC complete off, same problem. I found one shop (Tire world) in Brampton, Ontario who does tire shaving. I'm going to get them shaved and let's see what happens. If problem still continues than transfer case oil change which is also due (60k miles). If no luck after that either, than going back to factory setup wheels and tires. I know transfer case on these cars are expensive.

Perhaps you could search on ebay or whatever auction site is common in Canada and try to find 245-265/35 and 285/30 tyres and play with a few different ways to do it?

I'd really be curious to see what happens with your tyre shaving but I'd be worried that you're going to remove some tyre life on some nice expensive tyres!

Not worth doing for the questionable benefits.

Thanks Walt, I associated it with individuals that shave rims to change the offset, i figured it operated on same principal..

but I guess when you say it like that...tire shaving does no more damage to the "integrity" of a tire than do doing a proper burnout....

I would suggest that shaving does absolutely nothing to the integrity of the tire. I would hold that there is no such thing as a "proper" burnout when you are talking about the life of a tire. The extreme heat generated in a burnout or multiple burnouts will most assuredly negatively affect the integrity of the tire.

Tire shaving generates the top performance of a tire. Unfortunately only for a short period of time. As Walt said If you do some burnouts it is also like shaving but the tire received several heat inputs and looses performance as he hardens up.

I agree...Proper...meant just before making a run on the track to heat up tires and make better traction... either way... beneficial for and in the right situation. I hadn’t paid attention to the process of shaving, or it had never been presented as an option, usually I would just get new tires... learned something

[Walt White Coupe]

I agree, that would be a proper burnout.
