Tyres - Heavy Duty rear required?

Hi all.

Getting close to ditching the original Metzeler Z8s from the GRiSO, and wondering if the GRiSO demands a “heavy duty” spec for the rear tyre or not? I know the GRiSO is no lightweight, but it’s not a massive sports tourer with 40kgs of luggage attached either. So, what is the general consensus here?

Thanks.
Brent.

Brent, I'm on my second set of Michelin pr5's. I got 19,000 out of the last ones, but I ride like an old man.

It's no lightweight either. I like the Michelin's. The PR4 was great. The PR4-GT, which was designed for those massive sport-tourers with 40kg of luggage was even better on the GRiSO. Make of that what you will. They are no longer available. So far, the R5 I have on the back now is performing admirably.

Thinking of having a lash at the Pirelli Angel GT2. I believe that these also have the heavy duty version, hence the question.

Hi Brent

I put the Angel GT heavy duty ones on mine last year and they are so much better than the originals. So far about 4,000 miles and showing very little wear. Very happy with them.

I found out that the mighty GRiSO eats tires rather easily... between the torquy mill and heavy weight to slow down, both tires are short lived.
I tried pretty much everything on the market and the stickier tire I mounted on the bike was the Conti road attack... grabs even better than my beloved Dunlops. But I can only get 2800 miles or so on those Conti, yikes!!
I will admit that I don't ride like Grandpa yet and I live in Florida which is simply flat with 11 turns in 300 miles maybe, lol.
Any other brand I get about 4500/5000 miles on the rear with about 6000 up front.
Hope this helps...

I don't think that there's any markings on my original Metzelers that indicate a heavy duty variant. I've done 8,000kms so far on the OEM tyres, and their wear rate seems OK. Suppose if I plan on doing a bit more open country touring (with bags etc) a heavy duty rear may be an idea. Will keep researching the issue.

I've had the Angel GT's and the PR4's and now trying the Scorpion Trail II. Only 800mi so far but for me they are great. Time will tell.

Ditto beetle's comments as I have had two sets of the MPR4-GT's on my GRiSO (and Norge) and could not be more pleased with performance, including mileage (tho I care WAY more about dry/wet traction).

FWIW -- at least in the USA -- the 5 now comes in GT that fit GRiSO, [You must be registered and logged in to see this link.]
