I've got a friend who needs new tires on a 250 blaster,mostly for trail and hard pack but some mud.He wants to go wider on rear tires and also something that is more flat across than stock tires,any sugestions would be really appreciated.

 

Stick with the same tire size unless u want to checge the sprocket gearing. Hole shots are a good tire but are a soft tire and dont last as long. Razrs 6 ply are almost bullet proof well not really but they are a very strong tire and it will take alot to put a hole in them. The prices are about the same between the 2 brands. i would go with the razrs. These tires also have the flat profile compared to the stock oval tires.
