Front tire mounting on the rear

Hey guys, quick question:
I remember reading somewhere if mounting a "front" tire on the rear, I should reverse the rotation arrow shown on the tire sidewall, because the torque loading is reversed (accelerating vs. decelerating) True? Opinions? (sure to get some of them )
Thanks in advance for any info

Some tires have a directional arrow showing installation front or rear. My avons had a front this way and rear that way.

Its world wide many many decades long practice to just flip tire rotation to accomadate the most expected long term load on tire, in front it to resist brake,on rear it engine power. New tires have two way arrows labeled front or rear rotation to simplify this. On one way labeled tires just reverse the arrow if installing opposite what tire use is labeled for - front or rear.

Its because the cords in tire case can act like Chineese hand cuffs, one direction of load tightens the other lossens and also the long diagonal seam to mate the rubber strip that becomes the tread, one way tends to buckle it up the other to stretch flat.

That's what I thought, thanks!!

I couldn't get an Avon at one time and was forced to fit a Bridgestone BT 45 (?) front on the rear. 1500 miles later and it was kaput even though I'd reversed the direction on it. The Avon Roadriders can be run at both ends.

Greetings,
Besides internal cord windings there is one other thing to consider, tread design. Some tread designs claim to fame is enhanced traction and/or how they channel water, which under certain conditions can be quite important.

I am putting 21" AM26 Roadriders 90X90 front and rear and since Avon does not make a rear specific tire in that size, I am putting a front tire on the back. Avon told me to install it backwards on the rear, they also told me they do not reccomend putting tires meant for front wheels on the back wheels because the tire construction is different for tires meant to be installed on the front.

Interesting a more modern tire like Brigstone would distort to death under Cdo power and speeds in 1500 miles. But still good to know even if it injures tires, mostly mileage lost not a dumper or exploding danger. In shopping for excessive Peel some of the only tires I can find with over 149 mph rating are front tires to put on back reversed. Manufacturers are known to give extra conservative advice for legal reasons. Most dangerous scenario would be if tire leaked air and the cords buckled to help it de-rim. That's horrific sudden crisis and sold me on rim clamps or substitute.

I wouldn't say the Bridgestone distorted to death. It just wore flat in the middle in that 1500 miles. Just not made for the job. I love the roadriders. I've been through a heap of them now.
Between my Buell X1 and my Norton I've bought 31 new tyres in 4 and a half years.

Flat wear in middle is not a matter of rotation arrow but amount of time not leaned under power, which is mostly a matter of conditions that discourage leans but allow ya to power up as ya like. Its about impossible to avoid flat center wear in pubic riding. Used race tires come with just the edges buffed up but mostly unworn curved center profile. Brit bikes with same size tires front and rear its common to move used front to replace worn out rear to use up its center and a new tire put on front, observing arrow rotation. Cheap BI tradition.
