    Front tire size? 110/90 or 110/80?

    I have a 1980 GS1000E and the front boot is totally shagged. It is a Bridgestone Spitfire 110/90 19 and considering how wooden the same was on the back it has proved effective enough. I used to trust the front end to stay put through the bends, but now it slides around like a lesbian during a mud wrestling competion, and worse still I get some nasty head shakes too. Out back I have a Cheng shin Himax which is great, and intend on using the same at the front.

    I have a Metzler "touring" tyre from a GS1150 BMW with about half wear that I am going to fit for now, though it is 110/80 19..

    What is the correct size for the bike, as I need to order today or tomorrow and wait a month or so for delivery. I am going to stay 110, but should I go 90 or 80 profile????? I know compared to supersports my speedo reads way more conservatively, and I assume the lower profile will speed up steering a little too, no?

    Thanks

    Whats with the censor? I can write shagged but not the word for lady with desires for females?

    110/90 is the correct tire size.
    With the 80 series, it's in the side wall. 80% as tall as wide.
    In the 90, it's 90% as tall as wide
    Will it quicken steering? yes a little. I wll you lose ground clearance, yes a little.


    Shagged, an English term ,not English language term.
    Hence the censor didn't catch it.

      Yes, I am totally offended by the word shagged. As long as he dosen't use bollocks, wanker or tallywacker, I guess I won't have to inform Frank to add this to the censored dictionary.

        The front tire is listed as a 3.50/ 19 = 100/90/19
        4.50/17 = 130/90/17 rear

          Thanks for the quick responses!

          As to the censor not catching english words, how odd. I wouldnt dream of using the word wanker in this forum, as it wouldnt be right, I could substitute knackers for bollocks if that caused less offence. I bet I could get well creative in Spanish though.... So for those with sensitivity issues, stop reading about here. Kindest regards. CJ
