I would like to change some rear tires from a 26" OD tire to a 30" OD tire. I running a 350 tranny and a 9" ford rear end. Other than confusing the speedo, are there any reasons why this might not be a good idea. fenders are not an issue.
Along with the speedo error the height will have some effect on the final drive ratio, it reduces the rear end gear ratio approx 10-15 %..so if you running say a 3.25 rear gear it would perform like your running a 2.73 ( give or take)....
