Yes a 140 will fit. I have several wheels with 140s mounted.

A lot of people have been raving about the Michelin Activ. Not sure of the price but something to look into.

Recent raves about the Activ tires have brought new interest in these tires.  One thing about the Michelin tires I've found annoying is the lack of data on the Michelin site.  No mounted tire dimensions, no rim widths specified,  seems they want the buyer to have to contact the dealer for this info.

For anyone interested in this info I've found some Michelin data sheets at the Motorace site.  The point of interest here in discussing tire and rim fit sizes for the GS is the preferred rim width for the 140/70/17 Activ is 3.5" and not 4.0" as most all previously were.  Could be we have some GS/EX500 riders at Michelin.

Until now the prefered rim width for both 140/70 and 150/70 tires has been 4.0" with the 3.5 rim being an approved fitment for bias.  Now both Pirelli Demon and Avon Roadrider are designing the 140/70 for a 3.75 rim making the profile very close to preferred shape for both the 3.5 and 4.0 rims, I like that idea.

So theoretically I COULD get a 150/70 for it but the tire shape would be out of whack ?

btw - thanks for the reply and the work you put into it bro 

Your welcome, but it's not as much work as my long winded posts might indicate.  I keep up to date on tires that can be used on my bikes, keep a pile of the data sheets printed from the mfg tire sites on hand, and pick up the print copies of the tire guides from Metzeler, Pirelli, Avon, and Dunlop that have fitment guides and tire dimensions at the bike show every year.  Can check and/or confirm memory quickly.

No, a 150/70 on a 3.5 wheel would not be out of whack;  the shape would just be slightly off from the optimum and in my opinion it would take a very good rider to tell the difference.

I agee with the generally held belief that all other thing being equal the OEM size tires will probably give the best handling.  But all other things are not equal when you have a 3.5 wide rear wheel.  Sport touring radial tires generally come in a minimum 150/70 width and supersport tires come in a 150/60 minimum width so it's necessary to compromise on the fitment a bit to get the superior features of these radial tires.

Well worth the compromise in my opinion and I was real happy with the 150/70 Lasertec I used last year and am even happier with my current 150/70 RoadAttack.  Tires I've used on the GSs:

So far I have not used a tire/rim fitment that was not approved by the tire manufacturer on the GS's.

Well Jack , I went up to the shop and we finally decided on a 140/60 . It's definately smaller than i wanted , but it had a lot more rubber on the ground than what I currently have AND I won't have to modify the brake mount or chainguard . I'll post back after I get it once I know the brand , etc ... it's not one listed on your log . Whatever it was they get a good deal on ... they said it's Yokahama rubber made in China or Korea , but it's supposedly a LOT stickier than the Barracuda I currently have - just barely tapping the rear brake will lock my current one up with little to no noise , as it's a really hard compound . I RARELY ride on the highway , so the profile and the softer compound is what sold me . As i said , i'll update ya as soon as I get it (probably tuesday) . they also said if I didn't like it I could return it for 75% of what I paid if it's within a week or two . I'll probably move the rear brake brace out some and Dremel the chaingaurd to get the Conti-Road Attacks front AND back later this summer ... they look freaking cool lol (which shouldn't matter , but it does just a little for me hehe)

Again , thanks for the help Jack
