DMFT, ThanksDMFT said:If the Blur you're looking at HAS V-Brake bosses on the rear, a 2.24 WTB Moto and 2.4 WTB Mutano are ging to be the biggest you can get away with pretty much.
If the bike has NO V-Brake bosses - You can fit a 2.5 Maxxis DH Tire if you'd like, there's alot more room in the updated swingarm.
