salam,
i am in the same dilemma, i have alto 40k driven and need to change its tires. been using dunlop sp sport for 5 years.
i have 165 installed at the moment, but i have been reading lately. i guess the max size i should go for is 155 which is a safe bet.
and there arent any michelin or continentals available in 145 or 155
please help...?
