OK, so why shouldn't we rotate tires?(8 posts)

OK, so why shouldn't we rotate tires?SCY

I'm only asking this question at 1 a.m. because I got a moderate case of insomnia.

There was an earlier thread with the consensus that rotating the "bad" rear tire to the front would compromise safety. My question is this: what's the worse case scenario with a worn tire up front?

Does a squared off tire up front handle noticeably different? Does a worn tire up front actually blow out or blow off the rim (which has happened to me with an OK looking tire)? I mean, if the tire doesn't look obviously scary what is the worse thing that could happen?

On a tangent, what happens if you don't change your tires when they look worn? Do they just flat out, or do they blow out and make you crash? I'm asking these questions because I've never ridden on an obviously worn tire.

you'll never go anywhere. That's the whole point of a wheel, it rotates.

Oh. Never mind. Back to sleep now.

The answer is you can - just be sensible. Worn tyres side in the wet more, get more flats, and are more prone to blowouts. Better that on the back than the front, for the obvious reasons. So don't wait till your rear is nearly bald then put it on the front when you get a new rear - as if you would.

If you can't sleep - get up and sway the front and rears round - that you you'll get nice even wear....

There are two thoughts regarding rotating tires.

1st: When the rear tire starts to show wear and square off, usually around 500-600 miles, rotate once.

2nd: Don't rotate. You want your best tire on front. I get around 2K on the rear, twice or three times on the front. I just buy one tire at a time and install it on the rear. A couple of times a year, I'll have to buy two new tires. The reason is the rear tire is the one that carries most the weight and is subject to stress. Do you want a worn tire on the front or the rear? The front is the steering wheel, to experience a flat or blow out can cause a crash (been there done that). I want my best tire on the front.

Everytime I add a new tire, I change the rim tape (Velox), the best insurance against rim punctures.

Anyway, I'm lazy. It's a big hassle to swap tires. It's easier to just replace one. I tried rotating and it didn't seem to make much difference. I seldom go full life on a tire, they usually get trashed somewhere down the road due to a sidewall cut.

Also-when I start to experience a lot of flats and the tire is worn, thats an indication to me that it needs to be replaced.

If my tire was worn as you suggested, why not just toss it and move the front one to the back, then buy a new one for the front. $40 dollars is pretty cheap insurance when you think of what it might cost you if you have a blowout on the front going down a monster hill.

Its fine to rotate, you can probably lengthen the life of your tires this way if you have the time and desire to do so. Just dont delay too long. You dont want to put a square one up front or a thin one. If this tire fails it could possibly get ugly. The rear wears faster because it is delivering 100% of your 1/3 horsepower that your legs put out. You can just hear them wearing out when you stand and climb a steep hill!!

Yes. I replaced my old tires that had developed shoulders after 2000 miles. I didn't even have to ride the bike to feel the difference. It felt lighter even when I was just leading it by the stem. The ride was much improved as well. I shouldn't discount the psychological effect of getting new tires, but the rolling resistance felt lower (i.e., I felt fater), and the cornering felt grippier.

...you don't mind, it don't matter.

1st - don't ride on seriously worn tires, front or rear, unless your life lacks excitement.

Rotating your tires is a personal thing, right up there with changing your underwear, but you do it with car tires so it's not exactly a wacky concept. It's all a matter of if you want your tires to wear evenly and together so you buy a pair, or if you want to buy your tires one at a time. BTW - you don't wait until chord is showing on the rear.

True fact: your riding won't suffer and you won't crash 'cause of it.

I don't think we're going to change any ones mind that has a firm opinion on the matter on this forum. For those that are undecided just give either approach a try.
