I just purchased a new front tire and went oversize again (not huge) 2.10 against a 1.95 rear.
Both are round profile IRC Mythos xc, It seems 2.10 is the biggest xc tread they have.

I did it last winter, spring and really liked the feel. I lower the front air a fair bit and run a firm tire rear.
Bikes more responsive rear, and the bigger front seems to help pull into corners.

I was going to try a 2.25? But wasn't sure it would fit\ feel good. Anybody run major difference tire size?

I used to see lots of bikes with larger rear tires, not so much anymore....

I find the bigger front improves handling\ bigger rear doesn't, especially a flat profile rear to a round front.

?

The bigger front is true. I'm running a 26x2.5 michelin comp 24.1 on front and a 26x2.2 michelin hots on the back.

It's extremely common to run a bigger front that rear. I used to run 2.7 front and 2.5 rear, now on mt new bike it's 2.5 front and rear.

I was wondering, would a 2.7 front and a 2.35 rear be too much of a difference?

I always run a larger front/smaller rear... the front is more stable into the corners this way, absorbs hits better, and then the rear carves and accelerates nicely.

I think i'm going to try 2.1 to 2.5? in the spring. Hope it fits--.
The IRC is a front designated tire--but the xc treads on the rounder under 2.25 tires run o.k front or rear I find.

Thats how I started running oversize -tire sale found a bigger IRC that I wanted rear and I was matching treads.
Got home and it was designated R, but the tread was more angled across the tire and had one less knob to the edge\ higher profile -fine for front.

I was trying to work out 'squirm' on pavement and hardpack. I found I don't mind a rounder rear -tho it can pop off small rocks. The ratio difference SEEMS to help force the rear tire down for gravel climbs.

I also did it as a kid on jump bikes + motocross uses the same idea.

Well, maybe some other riders will hook up a new combo they like.
