Direction of rotation

Dunlop k81 410 19 does it really matter or make a difference in handling

Tyres are bonded for acceleration and for braking I believe (hence the direction arrow's for front and back fitment) and not for handling
I'm sure someone will correct me if I'm wrong
Cheers

The answer to this I was given is the "tread splice". The tread portion of the tire is manufactured as one long strip which is is wrapped around the carcass and the ends are cut at an angle and overlapped when bonding. This overlap is done in a direction that braking force on the front tire will not force the top layer to "peel" off and in the opposite direction on the rear tire to prevent this under acceleration.

That's my story and I'm sticking too it!

There was a time when 18 or 18 inch tires were very hard to find. The advice given to me when I went to replace tires on my friends Triumph was to by two front or two rears, don't recall which end was not available, different sizes, of course, and mount one of tires' in the opposite direction of rotation, sort of complimentary to the previous replies. K 81s are dog shit made into rubber...

Best.

I think tread splice has been debunked, and hydroplaning is the real reason. The thread linked below has some good research/references in it.

"I had a set of Avon Roadriders installed at a dealer once and they mounted the front wrong. I wasn't sure if it was a big deal or not a big deal so I called Avon Tyre, they told me the tread pattern on the roadrider was designed to shed water away from the back tire and being mounted backwards, would not harm the tire for grip or safety or even handling, but it would reverse the water direction and funnel it all to the rear wheel. and since I am not a pansey and ride it torrential rain to get places I went back to said dealer, told them and they re-mounted it correctly as the risk of hydroplaning was increased a lot. They have universal front/rear tires and have instructions to mount in one direction for front and the opposite for rear because of water shedding etc. This is the roadrider tyre only. I did not ask about any other model"

Directional tread patterns - myth or fact

Mounting directional tread tires. In brief, upon discovering a tire mounted in reverse to prescribed rotation what should one do? This raises the salient question what does directional tread actually do? Note, this is not a thread about off road, agriculatrual or asymmetric tire construction...

That explains a lot. I never liked K81 tires.

Do Dunlop not have a customer help desk?? As alluded to above, Avon are very on the ball concerning customer technical queries....
