Need Tires

Website is not accurate. Me and a lot of other St1300 riders in the Netherlands use the Road 6 in the original size.
Even the local garages telling us that it is fine. The Tire has the same load index and strenght.

Call or email Michelin with your question.
 
The difference in circumference between a 180/55zr17 and a 170/60zr17 is -0.8% for the 180. I don't see what would be the problem in mounting one unless the swingarm clearance is too tight. I similarly oversized a rear tire on a V-Star 1300 to use Michelin Commander IIs to no Ill effect

I am currently looking for new tires and I came across some information that I felt was good to share. I know many riders of heavier bikes that exclusively buy GT spec tires - currently this only includes the Bridgestone T32 in ST1300 sizes. I reached out to Dunlop about the Roadsmart IV, as they sell a GT spec and SP spec in Europe, but do not have that designation in North America.

Here was their response:

"Thank you for reaching out to Dunlop Motorcycle Tires. The Roadsmart IV available in North America is equivalent to the European GT version. The Roadsmart IV is suitable for a 2003 Honda ST 1300 and meets the requirements."

Perhaps this was well known, but I thought it would be good to share if anyone was scared off since the Roadsmart IV is not listed as GT spec.

A pair of Roadsmart IV's can be had for $163.95 (front) and $185.95 (rear) + tax and shipping in Canada (so CAD). They are quite an attractive choice at that price.

Look for RS III's... if you can find them they are typically pretty cheap.. .running 2nd set on my RT.

GT spec tires haven't been out all that long, for years heavy bikes just used whatever...

Tire manufacturers kept introducing tires with 'increased mileage'... we should have 40,000 miles motorcycle tires based on all those yearly ads increasing mileage... lol....

Because the rim is not large enough (width) you end up with a different profile for a 180 wide tire than it was designed for. It's very possible this difference is negligible going from 170 to 180, but there is a difference.

remember that 10% better mileage of a 5000 mile tire is only 500 miles ( your mileage may vary) read the fine print:nuts: :rofl1:

The GT version is marketing. The Road 6 is exact the same as the GT version

not true GT versions have a stiffer sidewall Michelin calls it "Reinforced radial x technology" standard version uses "2CT+ Technology". Bridgestone Gt version uses (from what I remember) polyester and a rayon ply to stiffen the sidewall and 2 polyester ply sidewall on non gt version.

I am a strong Michelin GT5 and GT6 tires for this bike. Great in the dry as well in the rain as well as a fairly high mileage tire (7-9,000 miles).
 
Well, I did email Michelin out of curiosity, and this was their response:

Thanks for contacting the Michelin Consumer Care Team. My name is Richard and I look forward to helping you out. You've been assigned case number ********. This will allow my team to quickly pull up your case details if any further questions arise.

Thank you for you for your interest in Michelin Motorcycle Tires.

In researching your 2003 Honda ST1300, I find that we do not have a recommended tire for your motorcycle. This is is based on the specifications from Honda.​

Not sure I would cross the Road 6 off my list, but it's interesting they make a front tire in our 18" size, but don't recommend it for the ST1300. How many other bikes can possible use that tire size?
 
Even in Germany, Michelin has approved the Road 6 for the ST1300.
I'm not allowed to fit any other size, as the first police check would immediately stop the ST and I wouldn't be allowed to ride another meter.
In Germany, we have to present the motorcycle to a technical inspection association every 2 years. costs about 100 dollars. The slightest technical defect leads to the motorcycle being taken out of service.
If there were a 180 or 205 tire on the rear, believe me, the inspector would drop dead on the spot.

Since I live in Germany, where large parts of the highway are not subject to speed limits, I sometimes drive at 125 miles per hour over longer distances. The Road 6 without GT can cope with this without any problems and the police don't say a word.

That is what I said. It is the same in the Netherlands. So many people with the road 6 on their ST1300 in the original size.
