tires in reverse direction.

What are the advantage and disadvantange to run the tires backward from it's intentional direction? Since we have almost all trackdays running CCW, the tires on the left side is worn but the right side is still looks good, what is the effect to turn it around or run it in reverse direction?

You have to use the GP shift pattern and your clutch works backwards.

me thinks it shouldnt make a difference. Only thing I can think of that would change would be the direction of the tread pattern. The tread is designed to sweep water out and away from the center of the tire. Reversing it would sweep the water to the center...but you probably aint gonna be doing a trackday in the rain.

But on the other hand, I dont really know shyt. Id say wait for someone who knows what they're talking about to chime in.

Most tires these days are made with 0 degree belt construction, so direction isn't important like it used to be, especially with slicks, where directional arrows mean essentially nothing. With DOT tires, the tread is usually directional, but but it's optimum for channeling water, not really for dry pavement traction.

But, that said, it's really not a good idea to try and save a few bucks by reversing tires after some time on the track. With fresh rubber comes safety, predictability and confidence. This is a false economy.

I've had tire vendors tell me it was "OK" to run it "backwards", but I still err on the side of safety. I'd rather spend a little more to get fresh tires than spend a lot fixing the bike or myself.

I have done it in a pinch, but it is not what I would normally do. The tires will work just fine reversed. Just be aware that the first lap or two they will feel a little loose as you scrub them in.

I've been doing it for the last 2 years (in dry conditions) w/o any problems. Search the interweb (other forums) and you'll see many guys testifying to it's great results.

Earlier this year when RideSmart hit TWS (Texas World Speedway) (CCW) and Cresson twice (CW and CCW) in about a 1 month timeframe I switched my tire direction 3 times. (Diablo Corsa 3s)

If it makes you feel uneasy, then you probably shouldn't do it...

Thanks for the inputs. I need a new set of tires for my street and track bikes. I am broke and trackday is coming up. Money save by running the tires backward vs. money save by repair wrecks and body. The latter seems more logical but I have been down even with new pair of rubbers. Maybe, I should just run it this time to see how it goes, beside I am 2 slow.

I am not trying to be a smartass here and I am not against people watching where their money goes.

However, with this topic in mind I find it hard to justify the risk.

Deferent situation but how many people do you know, or even yourself, parks a $30k or more vehicle in the driveway so you can store $10k or less of in the garage? Exceptions do happen, but the general reasoning of such a thing just doesn't add up to me as a "great" idea.

I park my car outside, but thats because my bike and tools are worth several times what my car is. Just attempting to make a point that some things aren't worth pinching penny's over and you can always save a buck or two elsewhere.

believe me, it's been thought over and been told many times over as in previous posts. The problem lies with if it works great/fine in reverse direction why not do it? It's just like having a nail in the tire, some would run it some won't.

I did it at TWS (Texas World Speedway) this past weekend. Felt the same. Ran just as fast (a little faster). I'll do it again if needed!

Ask your vendor, usually its perfectly fine.

But we've only done it w/ new tires. Not used ones trying to save money.

..yep, I have done it this and last season without any issues at all.
I only do this in the dry weather though (tread should be properly aligned then).
Otherwise, if it is nice, I run it and never saw any difference.

As dhdrider says, if you are not comfortable with it, do not do it (you will not be mentally ready for it and will blame tires if something happens). I accept the choice as my own and have never had issues (did it on Pirellis and Michelins already).

your tires. Your bike. Your decision.

No offense, but I think this is a really bad example.
