Tire Grooving: Opinions

[DieselTech]

Ok guys & gals. I put some Bridgestone Battlax 120/90-16 motorcycle tires on my ebike. They tip the scale in stock form at 11.2lbs each. About 6lbs heavier than a stock ebike tire.

I would like to put these tires on a diet, soo I bought a nice tire groover. I also would not mind achieving less rolling resistance.

Any of you want to chime in on a pattern to cut in these brand new tires. I just jotted this down on the tire to give you guys & gals my idea. Feel free to tell your thoughts.

Thanks.

Smooth and hard rolls the fastest.

Yeah I know that. I am mainly looking to reduce the weight of these meat eaters!!!

I think the weight is worth the extremely lower possibility of flats.

What size rim is this?

It is labeled as a 20x4 fat bike wheel. But I put on 120/90-16 Motorcycle tires on it.

Most of that tire weight is in the carcass of the tire. 4 ply sidewalls with reinforcing bands. Not likely more than a pound of weight to be saved before getting too radical.

I have a similar dual sport tire on my Hawk and they easily weigh 40% more than the off road knobbies that came off of it. The carcass is so heavy that they need 10 less psi of air to support the same load. 30 vs 40 on the rear. 28 vs 34 up front.

Yeah I been talking with some folks & they thought I could get 2lbs out of it. But that is really cutting it up!. Yeah I've been running 18psi in the rear & 16psi on the front. Lmao I think I can run these bald & then cut a street sport tread pattern in them.

Leave the tire alone weight loss isn't gonna be much besides all those grooves ya cut are just gonna be gravel picker uppers
little rocks stuck in the grooves
When or if ya wear down the sharp edges on the knobbies just cut em sharp again

That's not the right approach. If you want to shave off some weight, jack up the rear whhel and start the engine. Get it spinnin' real fast then hold your grinder against the tread. Seriously......... the damage you do to the tire is not worth the trade off for weight reduction.
