Hi guys, having trouble getting hold of a 3.75/18 rear for my 550. Can I put a 4.00/18 on the rim? Rim is original spoked.

Yes, you can. We all do.

Sorry to hijack, but ive also got a tire question. Would these work for a 1977 550 F2? Which sizes for front and rear?

The biggest on the front would be 100/90/19 and the biggest on the back would be 120/90/18. Can not see a 120/90/18. Some people go up to a 130/90/18 but, it depends on the tyre manufacture. Can not remember what make of 130/90/18 i put on a 550 but, it did rub on the torque arm/brake arm.

I really like Avon sm mk2 400/18 as a rear tyre, best grip for winter of any bike tyre I ave ever had fitted, I started using them due to the square tread profile being good for my sidecar outfit, but caught short of a legal tyre on my bmw r80/7 I bunged a spare one on and found they are truly excellent solo bike tyres, if they handle that well on a huge bulk like the bm, and let you crank it over enough to touch the pegs down on damp roads then they get my vote., think I had Avon roadrunner 100/90 19 up front in those days thanks to a mate getting a job lot of them cheap,the ribbed look did not inspire confidence, but they were good on solos, but showed their limitations on a sidecar, ploughing streight on out of a t junction if too much power was laid down on full lock, though they were very old tyres, hence the price being low. Remember this was on a sidecar, they have their own rulebook. On a normal bike even the old tyres were great.

I use Bridgestone BT45s on my 500; 100/90-19 front & 110/90-18 rear. Can't really fault them.
