I am shopping for new tires for my 09 raider. i have read as many posts on the subject as i can find. but i still have questions about switching to a 240 rear. is the full tire size 240/40-18 or does the 40 change also? as for the front tire, i have not seen much info about different brands to replace it. i am very dissatified with the metz do to them dry rotting within a short period of time. any info would b helpful.
