    I recently purchased a Kenda 130/90-16 Cruiser S/T rear tire for my '83 XJ750 Maxim. (I don't ride hard or corner fast).

    There is not much tire to driveshaft tunnel clearance, but there is some.

    It is the correct size tire & I know that tire dimensions vary from brand to brand for the same size.

    What clearances do you guys out there have & what tire are you using?

    I have a tad less than 1/4"

    I'm running the Kenda Challengers, I love them. Pretty sticky when they warm up. As for clearance... I will never fit anytihng wider in there I can tell you that. Although I would really like a little more rubber back there.

    thats the tire i run, and 1/4 inch sounds about right
    there is a bead of weld there that can be filed down a bit, that might get another 3/32 or so

    Specs say a 120 tire is what Yama designed the bike for.
    No wonder yer having Clearance issues... 130 is the wrong tire.
    NOTE: a fatter than stock tire.. Does.. degrade handling, noticeably.
    The Folklore idea that a bigger tire is better is simply the opposite of reality on a Motorcycle.
    You need a tire that designed for the rim width.
    Gotta change rims (in the v Least) before fooling about blindly with 'bigger' tires.

    Danilo,

    I am not fooling about blindly !!

    The specs for my 1983 XJ750K call for a tire size of 130/90-16.

    That is from the CD set put out by this forum XJCD v4.04 under "Parts, rear wheel"

    The Yamaha Owners Manual also states it is a 130/90-16.

    The Haynes Manual also lists 130/90-16 as the correct size.

    That is the tire size that was on the bike when I bought it.

    Please try to be more polite and don't accuse people of "fooling about blindly" until you know for certain they have.

    I've been around for nearly 70yrs. I am a retired Chemical Engineer & I am not in the habit of rashly changing things.

    Thank you & have a nice day :D

    I'm pretty sure I'm supposed to have a 130 back there? I could be wrong, but it stays none the less.

    Secas have 120 X 18 but Maxims have 130 X 16.

    Hey, Goat. I've got a 130 on my X and 1/4" clearance on the shaft side would be generous! I haven't had any rub, but I don't do much in the way of hard cornering either, mostly nice long swoopers.

    Now, let's see... What tire is it? Might be a Spitfire.

    Thanks all. As some of you have a similar clearance, I can breath a little easier now :D

    I've never had rubbing issues with my 750 and I've ridden pretty aggressively on several sets. I run a dunlop 130/90-16. Tires expand more from the center out rather then left to right when warm and spinning. Oh and grinding/filing down welds is a bad idea, i heard that weakens the weld. may look sloppy but thats the strength in the weld.

    I corner like a wild man or try anyway! on my Maxim... A little more in the rear would be nice though.. It handles well for what it is though.

    Ooops Guess it was the Seca size . Apparently 'Old goat' is a an apt name choice. The propensity to 'Up' tires sizes .. on the same rim.. is errr 'widespread' in MotoDom. Not clever.
    Want decent grip ? buy a decent tire Bridgestone BT45's is the minimum standard IMO. Tire contact patches onna Bike are tiny and there is only 2 of them. Not the place to save a fistfull of $$.
