Help!!! I just got new Pirelli MT75's mounted on my girlfriend's Blast and after struggling to get them back on I noticed that they're mounted backwards (counter rotation) Most likely the shop assumed it was left hand drive, like most bikes, since I just took them the rims. I guess I should have specified the tires orientation but I just assumed they'd look at the tires that were already on the rims.... then again they may have been mounted backwards too. I never really checked. Is it ok to run these like this or should I take them back and have them re-mounted? Most likely I'll get them re-mounted but I'd rather not go through all the trouble if it's ok. It's my girl's bike and I don't want her riding on anything unsafe. | ||

Do the work and remount. | ||

It wont hurt anything unless she is riding in the rain. Is she is riding the Blast to its limits anyhow? Doubtful I would make sure the shop knows about the boo boo though. | ||

The belting in the tire construction may be affected over time rotating against the arrow. Tire companies put arrows on the tires for a reason. It's happened to me once, years ago, when buying new tires. After that I marked on the rim with a Sharpie. In a vintage racing venue, I've run a 19-inch front ZR tire on the back, rotating backwards, because there were no 19-inch ZR rears available, but it wasn't going far. | ||

tires are made to take forces and push water away in one direction. If its backwards it could fall apart and it could push water under your tires (intsta-hydroplane) | ||

The belting in the tire construction may be affected over time rotating against the arrow. Maybe,but unlikely. Braking force on the sidewall is just as strong as acceleration........only in the opposite direction......which brings the question of pushing water out from under the tire under acceleration,compared to braking.......  | ||

Most likely the shop assumed it was left hand drive, like most bikes, since I just took them the rims. so the rims didn't have the old tires on them when you took it in? did you take them to a Buell dealer? | ||

When I take a wheel to an independent bike shop to mount a tire I make sure they know it is a Sportster motor and the drive is on the opposite side. | ||

I marked the inside of both my rims with an arrow showing the direction. That way there's no mistake, no matter if I or someone else changes my tires. | ||

Fix it, plain and simple. The rotation arrows are there for a reason. Take them back to the shop and let them know the tires are mounted backwards. No big deal. | ||

I'd fix it. Just a curious note about construction and tread design, though: Harleys in the past (early 80's?) had OEM Dunlops that called for the same tire to be used front or rear (16 inch bagger tires). They mounted one way (per the arrow on the tire) on the rear, and the opposite way on the front. | ||

Heck my Honda rims even have arrows on them so the Techs don't get confused. Too bad they couldn't read the arrows the first time they changed them. They remounted them for free. They need to be mounted properly. Barker, take a look at my PR2's next time and tell me if your logic "holds water" or not. Later Neil S. | ||

Why don't you call the manufacturer and ask them, don't take our word for it... I can only imagine their reply. It goes from the shops liability now directly to you, the observant installer. What if someone other than you or your girlfriend is injured because of an accident, regardless if the tires are at fault. You have knowledge, and you've shared it with us. It's now your responsibility! Not worth the risk IMHO. | ||

Thanks guys. You just confirmed what I was thinking. I'm gonna pull them back off tonight and take them back. I don't fault the guy that installed them really. I should have designated the rim orientation when I dropped them off. | ||

This is something that happens a lot. You are not alone. Long time ago, took a set of Moto Guzzi Borrani rims to the (then) best tire shop in Seattle, accessories & service, not a bike dealer. Shaft drives are certainly most common on the right side of the major brands, but not every tire changer knows it. That's when I learned to mark the rims. |
