Default Safety issue ..... Help !

I have lowered my front fender but a couple of the guys have said to watch for the growth of the tire when its hot .... DISASTER !!!


So any of you guys living in the hot states willing tomeasure how much your tire expands after a hard ride preferably Fatbobs with 130 front

I guess it would just mean measuring the distance from the rim to the mudguard before and after the ride .


ANY TAKERS ?????

I wonder how much larger the tire gets at 70 mph over sitting still, not considering temperature?

Actually, you hadmentioned checking it when hot and said it was OK. Like grandpawmoses mentioned, I was specifically talking about tire diameter growth due to centrifugal force when travelling at higher speeds. Like I said, not sure it's a problem, but I think fatter tires tend to do this a bit more. I'm not sure how you can find out to what extent this will happen though. Perhaps tire manufacturers have this info? Or maybe someone online has tested some different sized tires at different speeds which might give a rough estimate? Worth Googling maybe.

They do grow.

I have a polished underfender on the mudSickle to prove it.

I do believe my tire grew by approx three quarters inch.

I heard that Metz. tires don't have the "growth" problem. If your fender isn't any closer than 3/4", there should not be a problem, at least I don't think there would be, but, I'm not a tire guy.

I'd call the Tire manufacture pronto.... I think the Moco gets them pretty close to the limits...

The Confederate HellCat runs with the Metz880.

I've heard this too. If you saw any of the Eddie Trotta bike build on the Speed Channel show (don't remember the name), you saw that he won't use anything but Metz. tires because of that fact since he likes to build his bikes with the fenders slammed as much as possible.

I've run oversized tires on all my ricers and I typically get by with 3/8 to 1/2" clearance That's why I tried to lower the fender on my Harley it looks ridiculous no street bike needs that much clearance.
