Tire question...?

[Guest]

Hi,

I have two bikes that need tires.

GS750 1977
Will a 130/90-18 fit? Presently there is a 120/90-18 installed...which has a tube (spoke wheels)
Can I purchase any type of rear tire and put a tube in it? What size tube? They where listed differently from the tire sizes on one site I was looking.

GS750E 1983
There's presently a 100/90-R16...what does the R stand for? I found a 100/90-16H...will this fit?

Any info is appreciated.

Cheers,

Dave

The R usually denotes a Radial and in rare case a speed rating, depends where the letter is placed in the sequence. In your case I would say Radial on this one, the H is a speed rating. H=130mph The 100/90-16H is a non radial or as the other denotes a radial. And yeah the 100/90-16H will fit though remember it isn't a radial.

On the 77 750 you are pushing the width with a 130 on the rear. On my 1980 GS750E I installed a 5.10 (old time measurement to the new 130/90-18H) The 5.10 screwed with my handling big time. I went back to pretty much the stock size tires, cured the problem. The 120/90-18 is fine. The tube of the same size is what I would look for.

Thanks for the info it's much appreciated...I'll stick with the stock 120 for the 77 and look for a radial (R16) for the 83.
