What's better wheel tire combo. 24mm or 26mm and whats the difference is the 24mm less narrow then the 26mm or is the circumference less by 2mm. In other words is the 24mm a smaller tire or narrower then the 26mm and will the same tire fit the 24mm as the 26mm or no. The reason I asked I'm getting the Volvo 850 body and I don't have the BBS wheels that the original Volvo came with but I found a set of 24mm and 26mm I just wanna make sure that one fits, Thanks.
