whats a good size tire for a blaster i have 18x8 on their now its good but when you hit 5th & 6th gear it seems like its just spinning and not going any were. these tires are good for a track but maybe need a trial tire thanks for the help
18's are good for a track yes, 20's or 22's are better for trails. some people change the sprockets out to a 14 front and 38 rear when downsizing to 18's
