Tire sizing for an R100S

[bobinthemtns]

Okay.. it's that time again.. Puma needs some new kicks!

But after seeing BoxerBolshie's tire setup, http://www.bmwmoa.org/forum/showthre...158#post783158

I think I'm going to do the enduro route too since I seem to find myself traversing mtn fire roads a lot... (and I think they'd look cool as hell on an "S") But of course there's the sizing issues..

Now the Shinko 705's (the tires in question - http://www.shinkotireusa.com/product/product.php?id=63) for the rear they are available in 4.10-18 tubed type. I'm assuming that will fit no problem on the back wheel.

For the front however, they don't have inch sizing.... but it seems the general consensus is that 100/90-19 is the metric equivalent for the front, with a 90/90-19 fitting as well (but someone mentioned that the 90/90 size wasn't optimal for a 1000cc bike....?) The closest size Shinko makes for the front is 110/80-19....

I reached out to Boxerbolshie and he said the tires fit his bike with no mods needed- I'm assuming his bike (mid 80's R65) has the same size wheels as a '77 R100S....

So long story short: That back tire will fit no prob.... right?
And if I go with the 110/80-19 for the front- anyone seeing any issues? Or am I gonna die?!!! Haha
