Larger tires

[Jeffrey650]

Instead of 90/90-19 tires for my gs650gl could I buy a 100/90-19...would it fit on the rim.. And could you put a bigger tire on the rear like a 140/90-16 instead of a 130/90-16?

yup.....

but be careful, the majority will say and tell you it's no good for handling...and one should stick with the stock setup...

I went up one size front and back and found no issues on my 750E

FWIW, this has been discussed ad nauseum on this forum, in both the new and old tech forums.

The GS-information world is an oyster in your palm if you know how to use the search feature.

I wouldn't change either; on the rear, there is little clearance with swingarm, if the tire were to flex while cornering and hitting a bump, fun could ensue.

On all of our bikes (and one of them is a 650GL), we run 100/90-19 tires on the front. Yes, it gets a bit close to the fender, but it fits AND it virtually eliminates the typical speedometer error.

However, on the rear, the wheel is not really wide enough to properly support a 140, and, like tom203 mentioned, there really isn't much clearance to the swingarm.

SPEAKING FROM EXPERIENCE, I can say that one size up on the front works, but leave the rear stock.

I've had good luck searching by toggling "advanced search", then using the "Titles Only" function. You still need to sift though lots of hits, but it's easy to see what the thread was about this way.

Yes, and it would work even better if thread starters would use descriptive titles.

How many times have we seen titles like "Need help" or "78 750"? Makes it hard to want to look at either of those, because I don't know, without further looking to see what sub-forum it's in, whether they are looking for psychiatric help, help with their Buick or maybe even a bike. Since we now have a couple of "other" forums, that bike might be a Honda. If we are really lucky, the "help" they need might involve a GS, but it would still be nice to know which one and what the problem area is.

Personally, I might click on the "78 750" thread, but it would be on the second (or third) go-around, after I have checked all the other threads that piqued my interest. Why? There are several things about a '78 750 with which I have little experience, like VM carbs, spoked wheels, chain drive, points, different turn signal flasher. Put up a post about "78 750 brakes", I might be able to offer something because the brakes are remarkably similar, although not identical.

It only takes a few seconds more to add a few more words to the title, and it would make searches so much more meaningful.

I have the 100 on mine and it works fine. I never used a 90 so I can't give you a comparison on handling.
