The New Metzeler Z8 "O" spec
I guess I'm easily confused. Tires are one of the most debated and perplexing products we put on our GT's and GTL's. I think the manufacturers have been listening (somewhat) to our complaints of short life, especially from the Z8 crowd. Now I see that Metzeler has stepped up and offered their re enforced version of the Z8 the "O" spec.
Many GTL riders have replaced the Z8's with PR3's, RS2's Pirelli Angel GT's all in an effort to get more mileage out of them. I have approximately 6700 miles on the original Z8's on my GTL. I'm soon to be in the market for some tires as these are cupped and showing some wear. I'm well aware that there are a lot of different factors effecting tire life such as, road conditions, pressure, temperatures, riding style, etc.
My question for the tire guru's here is can anybody make sense of Metzeler's website and designations of the tire specs? What's the difference in the O, M, E, C spec's? When you pull down the menu, you can see all sorts of labeling with little explanation.
Here's what shows on the site for tires that will fit the GTL.
120/70 ZR 17 M/C (58W) TL (E)
120/70 ZR 17 M/C (58W) TL (M)
190/55 ZR 17 M/C (75W) TL (C)
190/55 ZR 17 M/C (75W) TL (M)
190/55 ZR 17 M/C (75W) TL (O)
I like Metzeler tires but not so sure these new ones will be any better than the other brands I've mentioned. Given the assumed price difference as well, the other brands may be even better. I've had high hopes for the Continental RA's but they can't seen to get their $h!!t together and bring a GT spec tire to market. Of course, as I'm typing this, Michelin throws out the PR4...
