Thanks for the link Muskrat. 100/90 is 3.25/3.50 for front and 120/90 is 4.50/4.75 for rear. (They don’t list the 110/90)
Will these be noticeably chunkier? I don’t want them to look too big. I’ve been in touch with the PO and he has a big box of spares to send me inc a new rear tyre but I don’t know what brand so I’ll wait for that to turn up, hopefully next week.
Cheers
Pete
