Tire question.

[Guest]

Will a 140-90-16 tire fit on the rear or a 1982 GS1100GK the original tire size is 130-90-16.

That should be on the rear (of) a 1982 GS 1100 GK

How wide is the rim itself? Even on a 2.5" wheel a 140 gets pinched enough to give the tire a triangular crown. I tried a 140 on a 2.5" wheel once and didn't like it. If you have a wider rim than that then go for it.

My question i quess is will there be enough clearance by the driveshaft.

My question i quess is will there be enough clearance by the driveshaft.

Are you wanting a 140 tire on there for looks or because you think it will give you more traction?

There may or may not be clearance to the drive shaft, but that is not nearly as important as having proper support for the tire and maintaining the proper shape.

As Billy Ricks mentioned, putting a wide tire on a narrow(ish) rim will pinch it into a triangular profile and will actually give you a SMALLER contact patch on the ground.

Didn't know there was 16's on the rears of any GS..

Most of the L models are 16" rear Joe.

I believe that rim is 2.75" wide. A 140 will fit on the rim okay, but I'm not sure about the swingarm.

I believe that rim is 2.75" wide.

If it is, I believe that would be unique to the GK.

Not sure about the chain-driven 1100s but I have not seen any shafties with a rear wheel wider than 2.5".

I think all the 850-1100G 16" shafty rears are 2.75".

[Billy Ricks]

I think all the 850-1100G 16" shafty rears are 2.75".

That could be true. If they were running a stock 130 then a 2.75" wheel sounds right. The OP can verify that by checking the castings on the wheel.

I have three GS all with 16" on back 1981 gs 550 L - 1981 gs 650 l and 1982 gs 1100 gk.

Would you mind checking the sizes that are cast into the wheel and letting us know what they are?

I will check the 650L and 850L at the house when I get there in a week and a half.

FYI, the wheel sizes are listed in the Suzuki parts fishe. Most if not all 16" GS wheels are 2.75" wide.

Sure enough, it shows both the 650L and 850L wheels as 2.75.

I wonder where I got the idea they were only 2.50?
