How important is the reinforced sidewall as spec'd by BMW?

I see a lot of guys talking about putting on Michelin Pilot Road 2s and Dunlop Roadsmarts, etc. I'd love to run them to as Ive always been fond of Michelin tires for my cars and motorcycles. But BMW specs tires with reinforced sidewalls for their 2006+ K1200GT motorcycle such as the Metzeler Z6 and the Bridestone Battlax. Neither is a favorite of mine but they meet the BMW spec. Is there a valid reason not to worry about the sidewall reinforcement specs? I ride very fast and hard too.

Last fall I had a sidewall blow-out with the Pilot Road 2's. Michelin Tires at first told my dealer that the 2's were not recommended for the GT2, but changed the their story saying the tire was fine for the GT2 and gave my dealer a new set (front and rear) to put on my bike.

I like the tire for traction and wear. The Pilot Road 2's are very smooth turning into a corner, and I was going to get an extra couple of thousand miles out of them over the Z'6s.

I know that over in Europe the Pilot Road's 2's are popular for the GT2's, and at times they are back ordered over here in the states.

Bottom line: I feel save on the Pilot Road 2's even with the blow-out.

I have just put Pilot Road 2s on my 06 GT and found them to feel much better than the Z6s.

I checked with a couple of sources with regards the rating. The local BMW dealer towed the line and said BMW specify the higher loading for a reason so they only fit the recommended tyre.

My local tyre supplier advised that unless I was going to use the bike flat out fully loaded for extended periods of time, the Michelins would be fine.

We had a presentation at our local motor club a few years ago from Bridgestone and the rep had the same advice as the tyre supplier, he added that some car manufacturers specify a certain tyre design for noise or fuel economy reasons, and the most important factor is to ensure that the tyre pressures are regularly checked and matched to the loads they are carrying, and the tread is checked for damage.

The Avon Storm ST meet BMW's specification for sidewall strength and you'll find a number of high-mileage riders on this board extremely happy with them. They have excellent turn-in response, offer a far more compliant ride than the Z6 and provide excellent traction over all surfaces including wet ones. They are also the only motorcycle tire with a road hazard warranty. In Canada, they are at least 10-15% less expensive than the Michelins. I paid $300 installed and balanced.

I really enjoy mine.

My 2nd set of tires was the Road Attacks and there was a huge debate on this going on then. I put over 7k rock and roll miles on them without a problem. They are rated at 800lbs. I'd do it again, especially if you have a new set you're not comfortable with and want to give me.

I'll be sticking my 2nd set of P2's on the bike (already in the gearage waiting) when these are done.

Todd, I now have several sets of used tires awaiting the next stranding.

I just dont want to have to worry about a blow out when Im cruising through the desert at 100+ with all my chit on my bike. If I just putted around...No big deal. I wish these manufacturers (Michelin) would make a PR2 for our bike.

Michelin has the Pilot Road 2 B for the GT (rear only). The 'B' has firmer sidewalls.

I cant find anybody selling the 'B' spec Michelin Pilot Road 2s on the internet. Where did you get them? The Michelin Website doesnt even show them. Thats the tire I'd like to run.

Thanks,

Grif, Just curious, does your back tire have the B rating, because none of the tire sites lists a special B rated PR2 tire for the GT. Just want to make sure I don't screw up.

Thanks Mark
