I was just wondering if anyone has deviated from the factory spec rear tire size? You know gone from a 180/55 to say a 190/55 or even a 200 series tire?

It appears to me that a whole lot more tire could be fitted in the wheel well of the RT, particularly a tire with a slightly taller profile.

Here is my thinking. We have all been looking for that elusive long distance tire but one which grips. Obviously finding the grippy part is easy but the longevity is not so great on the rear. Michelin makes the Commander II radial tire with a V rating (up to 149mph) in a couple 17" sizes:
200/55 which would be approximately 1/2" taller and 3/4" wider.
160/70 which would be approximately 1/2" taller and 3/4" narrower.

Now michelin and the reports claim these tires get approximately 20k miles, AND they stick like glue even in the wet due to the silicates used throughout the tire compound. This is also what gives the tire its longevity.
So since I can get 12k or better out of a PR3 front, but only 8k out of the rear, I'm thinking this combination might even up the replacement interval.

Thoughts?

I run 42psi all the time, have on every bike I've ever owned. Under inflation causes most wear issues, but I'm not having wear issues I'm just plain wearing out tires ;)

beech, Really??? Yep I just started riding yesterday so I'll buy the ole engineers R&R'd, pffft... They actually went with the industry NORM, nothing new or special there. Obviously the RT doesn't have enough swingarm clearance for a 190 or 200, so narrower and taller would be the option.
The GS runs a 150/70-17 and ain't none of them flying off the road out of control, so obviously a 160/70 would work just fine on the RT. So my question was has anyone gone this route, not whether you approve?
Oh and nice little implied insult there at the end, cheap eh? Actually I'm far MORE practical than that. I RIDE, my bike doesn't sit. So where you might change a set of tires a year, I go through at least 4 sets. So lets set the record straight, it isn't being cheap as you suggest. It is a matter of practicality not needing to replace tires on the road constantly where you can't guarantee you'll find the tire you prefer to run. Yes I know some of the fellas here schedule and order in tires ahead at some dealer along their rout. I don't follow a rout, I RIDE.
Good thing I didn't mention the car tire conversion or I might have blown up on the spot :rolleyes:
