Re grinding a square tire

I got rid of my chicken strips today. With a grinder. And an 80 grit disc. My rear tire was starting to feel edgey from the flat spot in the center after 10,000 miles of highway commuting so I thought about grinding it round again. My coworker who is an expert body and frame tech and also a winning stock car- dirt oval driver was walking by so I asked him half jokingly if he ever ground rubber off of a tire before and he said "Only if you want to win!". It turns out that these guys buff up the tires between every heat to take the glaze off. So I borrowed his grinder and went at it with the wheel idling on the stand in first gear. No more than 15 minutes later I had a dust pan full of rubber and a nice round tire again.

over 20,000 miles, expect another 20,000 or more, still square and still sticks, whether scraping pegs in twisites or not leaning so much in freezing rain

You get 10,000 miles out of a tyre?!! And still more left?

You need to do a few more wheelspins. I'm lucky to get a thousand miles out of mine.

That is the stock IRC Roadwinner on my CBR250R. Fantastic tire for OEM. Sticks like glue in the rain and lasts forever. The front tire has no flat center and is hard to tell from new. I should get 20,000 miles out of that one.

Late 90's vintage Pirelli automotive snow tire? Must feel pretty sketchy making turns around town with such a sharp edge.

Actually, car tires "flex" to keep a good part of the tread on the ground. It never rolls up "on edge" (or on the sidewall).

Depending on the tire (and whether it's broke in or needs broken in), a little more countersteering pressure is required. nothing "sketchy" at all. :)

General Altimax Arctic, an experiment on the darkside that had been successful beyond my wildest imagination, slow speed handling is a bit funky but ya get used to it, at speed, you can barely tell it's not the stock size MC tire (slower turn in, but no different than if I had the same size MC tire)

I went with the General cause it was the cheapest tire I could find, not knowing if I was going to take it off in a week, for my purposes, my next tire will probably be a Nokian Hakkapeliitta

I ride in conditions that many people wouldn't even go out in in a 4wd SUV

Most 4WD SUV's are actually AWD or Fulltime 4WD, which is quite far from a "real" 4WD, you can get stuck with one of those. Plus SUV's are heavy and shitty to drive. I'd take a 4WD sedan if I ever get scared in taking my 2WD car out, which has so far never gotten stuck.

Yes they are. When I get one it's going to have solid axles at both end and lockers too. It's not snow I wanna drive through, it's rocks.

But I see where you're coming from, even the Grand Cherokee lost its solid front axle. Now the only new vehicle with a decent 4wd system we can get is a Jeep Wrangler.

The furthest away from a SFA I'm willing to go is a TTB in an Exploder or Bronco, and even those quit being made in '95.

And absolutely nothing without 4L.

In my country, that still gives me a pretty wide selection--
Chevy K-5 Blazer
Full size Bronco
Bronco II
Jeep CJ/Wrangler, cherokee, Grand Cherokee (with the 4.0 motor only)
Exploder up to '94
'84-85 4Runner (still some rust-free examples running around here)
Suzuki Samurai
Dodge Ramcharger/Plymouth TrailDuster

The one place I don't skimp is on tires. 10k? call it a day. You're not Mert Lawwill slicing his tires with a razor blade before The Springfield Mile.

Not skimping. It's still good. Proving a point to the car vs. bike guys that my bike not only uses way less gas than a car but is at least on par with total tire usage.

This could make a very entertaining thread all on its own.

F.W.I.W. I've seen Subarus climb steep slippery snow/ice covered roads where even old jeeps with Quadratrack (which locks all 4 wheels together in rotation) couldn't, with comparable tires.

I also had a 72 Dodge Coronet Wagon with posi and studded snows that wouldn't get stuck ANYWHERE in the winter. (with no added weight in the rear)
I honestly think it has more to do with the driver than the vehicle.

Sorry O.P.! Back to your topic.

problem with 4wd sedans is that they do not have the ground clearance of a SUV, traction does no good if yer hung up on the belly

deep snow is about the only time a SUV can go somewhere I can't with my V-Strom,
