Avon Storm 3D X-M Motorcycle Tire (Load Index)

Get out the Pop-Corn!

I use these tires on my 01' Kaw Concours. And other than some strange wear on the rear, they are sticky "enough" and inspire confidence and the front wears great. I pulled a Storm II off at 9K miles and had no cupping and nice even wear, almost looked new. I only changed it because I was heading out on a 4K mile ride to Baja Cal Sur. On a Concours (200 lbs. lighter)

Now on to the K12LT. OEM Meltzer's call for a 79V rating. "79" = 963 lbs. Load Index. "V" = 149 Max MPH on Speed Index.

New Avon Storm 3D X-M Motorcycle Tire P/N Info from Avon Site.
Front = AV65 120/70ZR17 (58W)
Rear = AV66 160/70R17 (79V)

This AV65 FRONT with a Load Index of "58" puts it at 520 lbs. on the Avon LI scale!

I depend more on the front tire and load it extremely hard when pushing a nice turn. I'm not sure if I would trust this tire 2-up and loaded. Having spent multiple years road racing, the front takes a lot of abuse, under braking the load is multiplied.

Maybe I'm missing something. Is this the STORM you guy's are running? My other option is the BT020-M Bias Front and Rear.

Re: Avon Storm 3D X-M Motorcycle Tire (Load Index)

I haven't bought tires yet for mine but the 58 load rating is what is specified for the LT and the W speed rating is higher than the specified V rating so I wouldn't see an issue. That is what the specs say for LT tires. 58V front, 79V rear. Why are you concerned. You wouldn't be putting an under rated tire on it.

Some good discussion on loading this thread if you haven't seen it yet.

Re: Avon Storm 3D X-M Motorcycle Tire (Load Index)

I haven't seen the 58V rating for the FRONT. That's why I started this. But sounds good to me! I know others on here like them, now it makes perfect sense. Guess I should have dug deeper into the front tire spec, I assumed F/R would be the same. Never ASS-U-ME. Lesson of the day.

BTW; I did read that "ALT TIRE THREAD". A lot of reading to pull little info. Some tires come in multi load factors and some have bias and radial in the same model unless you add a single letter to the P/N.

I found it in the BMW repair manual I have. Look under your seat at the plackard and you can see the GAWR load ratings front and rear for max load distribution. Most of your added weight will be distributed on the rear tire behind the center point.

Re: Avon Storm 3D X-M Motorcycle Tire (Load Index)

I run the Avon Storm 3D XM Motorcycle tires and really like them. The load index is fine for the front because I believe (from memory which is dangerous) that the front tire should handle 450 lbs+/- so you are fine.

Re: Avon Storm 3D X-M Motorcycle Tire (Load Index)

Well after a day of fumbling around on this World Wide Web!

REAR: Avon Storm 3D X-M Rear / 160/70R17 79V. I have many miles on this tire, and the testimony of how it works on the LT is true to my experience with it.

FRONT: Michelin Pilot Road 4-GT Front / 120/70zr-17 58W.

Though MIXED brand, they are both radials.

Looking forward to trying this Michelin front. I live on a DIRT ROAD. 16 years on the same road = Road conditions in the morning has nothing to do with road conditions 12 hours later. The sipping and additional edges might help keep the LT front going where I have it pointed under semi-wet dirt road conditions. (I need a GS)

I just ordered a Metzler to replace the Bridgestone currently mounted o the front. Attached is a wear chart I created showing how my front and rear tires have been wearing. I like the Stone on the back, but will not put one on the front again after getting only 4,800 miles on it.

Wow! Since this is my first venture with a K1200LT, I'm learning a lot. Good thing I like wrenching on motorcycles. And, it's a good thing this is not my only street bike. I'll gather my own tire wear report as I turn the miles and watch the rubber disappear!

This KLT project I've got going on will payoff real soon when my wife is riding with me in comfort. She has been pillion on a Sportster, K75s, Concourse and now we will be 2-Up on the best package I could ask for, the K1200LT.

Tires are fun to buy, a new set makes the old rides feel new again. Old bikes deserve to live-on.
