I've done some searching and there seems to be some reasonably priced Shinko SR 241 available in 18" in 350-18 size.
The question I have is, will a 3.5" wide tyre fit the rear swing-arm of the Alpha? Would the rim width effect this?
What is the widest tyre that will fit?
Shinkos SR241 run a bit bigger than there measurements. I know that the 2.75-17, 2,75-18 and 2.75-19 SR241 run about 2.9 inches wide on a 1.40 wide rim. I can also tell you that both the 3.00-17 and 3.00-18 SR241 come in around 3.33 inches wide on a 1.40 wide rim. I suspect the 3.50-18 SR241 would fit, but you wont have more than a mm or 2 of clearance between the tire and swigarm. I really think you would be happy running the 3.00-18 SR241.
