Just checking...

Ok to mix an Avon Storm 3D X-M front with a Metzler 888 rear?

Installed ME-880's on front and rear when I first bought the bike.
Front ME-880 now needs replacing after 16,000 (speedo does run about 10% high).
Still wasn't down to wear indicators but cupping was significant. Didn't want to take it on any long hauls on it.
Due to a puncture, the rear 880 got replaced with an 888. It still has good tread.

I bought the matching Avon for the back but thought I'd put some more miles on the 888 before replacing.

Just want to be sure it's ok to run the Avon / Metz combo for a little while.

Just finished mounting / installing the Avon.

Was a little concerned when I couldn't find a red or yellow dot.

Looked online and someone mentioned they are balanced before they leave the factory, ego no dots.

Either I got lucky or that's true.

The lite spot of the wheel by itself is opposite the valve stem, off maybe 20 degrees.

Took one 1/4oz to balance. Pretty much opposite the valve stem too!

Thanks for the reply.

I must admit, I haven't really paid too much attention to tire technology.
I just remembered from years past, your not supposed to mix radials and Bias ply.

I usually read about what others are using.
Then read reviews noting - how they wear, wet weather traction, sticky on dry roads, etc..
Then buy a set, install them and go.

After reading your reply, I had to re-school myself on Radial (Steel belt, along tread) & Bias (cords run at angle, bead to bead).
Then read on why not to mix and if mixed, use radial on rear.

That said, I went to the Metzler website and read that the ME888 is a radial tire.
" Innovative belt structure with a single ply of steel cords wrapped around a radial carcass at 0°."

Then to Avon's site to find the rear tire is Hybird steel belt and I've yet to determine how the front it belted.

Don't / didn't want to start a big tire stink or discussion.
Guess I was being a little lazy and just wanted to know if I was safe to run this combo.

I was on a trip a few years back. I had radials on the LT. Well. Make a long story short. I thought I had enough rear tread to complete the trip. Well. I did not. Cords started peaking through the rear. Rt 50 through Rowelsburg WV tore that tire up. So i'm in the middle of nowhere and need a tire. The only dealer close. That had a 160/70/17 (80 miles away) is in Romney. A Kawi/Suzuki dealer. They had a Dunlop D401 Harley Davidson model. I got there. Got the tire mounted. Finished the trip with 1K to go. Ran the bias Dunlop rear/Avon radial front for over 1500 miles. No issues. I then replaced the set when it was more convenient at home.

Thanks James, I'm on hold right now with Metzler USA.
I need to find out exactly what's what.
Read on Metzler's website the ME888 is Steel belted Radial. Metzler tyres catalogue - ME 888 marathon ultra

Then see this on another site - motorcycle-usa.com -tire evolution metzeler me888 marathon ultras/

"Metzler’s ME888 fits Harley-Davidson’s new FL Touring motorcycles in addition to Softails and Sportsters.
The bias belted versions are produced in Brazil while radial 888’s are produced in Germany."​

Just looked at my rear ME888, made in Brazil....

Thinking maybe I better just mount the new rear Avon and be done with this..

ME888 Steel belted?? First I've heard of it. Could be I guess. Maybe contacting them will answer that.

Off the phone with Metzler USA.

Question - "Is my Metzler ME888 Marathon Ultra, size 160/70-17 79V Reinforced a Radial or Bias tire?"

"Radial"
Tell him I have Nylon & Polymide written on side of my tire
Now it's "Bias"
Direct him to website which reads "Steel Radial"
Now it's both "steel cords wrapped in Nylon"

I ask for another rep

"Danny's gone today, I'm it"

Heading down to garage to install new Avon..

I would not mix radial and bias on a motorcycle. This isn't even recommended for cars.

I don't know about Metzeler, but the Bridgestone BT020 is a radial tire, except for the two made specifically for the LT which are bias construction. If you check their web site you will see this in the tire description.

It could well be the same for other brands and the customer service folks that answer the phone may not be aware of such rare exceptions. I doubt the LT tires are best sellers for any tire company.

Thanks Zeke.. Will do!

Have you run a 10% check on these? 39 /44 recommended on Avon's site.

yes absolutely, 43 front/48 rear. seems to be best. i have tried all different lbs. but using the 10 percent rule always gives me these numbers to use. have used those number for over 20 sets. seems to work for my riding style.

I had a very long chat with Avon regarding this issue and wear on the 3d XM. After the engineers at avon watched my video review they felt that I was running too much pressure and it caused premature uneven wear. Im not real sure about that but they recommended these pressures for the LT. Front 36-38, rear 42. I was running 40F 44R to find the 10%. I may retry these tires and revisit the review.

38 and 42 Really? Well. It would be the first set that doesn't run 42 and 48. I would like to know how they came to that analysis for that conclusion. Not saying they aren't correct. Maybe they are. Just want to know why. Ok. I'll try their recommendations for pressures on my Avons.

Well. I'm done. Didn't register within 10 days. And ordered online. Have to track reciept. But. If I get 10K or so miles out of them. I would be just fine with that.

We wont know until we try. I say, everyone using them should cash in big time on their 15K wear out warranty! Read the conditions first so they cant back out. Avon Motorcycle Tyres North America » ? U.S. Claims
Yes, always worth experimenting if a given pressure didn't yield good results.

I had good results with the forum consensue 42/48 with several sets of ME880s. I got 8-9,000 rear and 17-18,000 front with manageable levels of cupping.

I am now running BT020s after running one on the rear and getting more than 12,000 miles on it, but with a fair amount of cupping. My front is wearing much faster than the ME880, as many here have found, and may not last as long as the rear Bridgestone. Since the Bridgestone rear has a 48 rather than 50 psi max pressure, I am wondering if maybe slightly lower pressures might work better for the BT020s as compared to the 880s.

I have a later model LT so I don't think Avon makes a bias ply tire for the LT. I would try them if they did.

Regarding the 10% "rule", I would not get too hung up on that. It is at most a guideline, not a law of physics. Any pressure between the bike maker's recommendation and the tire maker's maximum are clearly fair game, 10% "rule" or no.
