I bought my 2001 WR426 with a Dunlop D750 120 80 19 rear tire. It's time to change it and I don't have any idea what to go with this time. I have read that the 18" wheel / tires give more sidewall to prevent pinch flats - is there anything else I'm missing out on by having a 19" rear? Is it critical that I use an 18" rear?

The front tire is a 21" d739 and is in decent shape, should I find a D739 for the rear as well? I ride mostly mountain trails with rocks, packed dirt and some sand.

I love the 739 for the rear in the desert. I run an 18 inch 120 though.

regarding 18 or 19.... I don't think you'll be any more prone to flats, but you will be more prone to dent the rim.

If I were racing (a lot), I'd want a 19 and not an 18. But, if you are happy with the way that it performs, then wait until you destroy the rear rim before you swap it out.

[COLOR="DarkGreen"]Ill bet 99% of people could get on a bike and not guess if they had a 18 or 19 on the rear

Cool, I'll see if I can get it off this week and have a 739 mounted. Been way too long since I've been out on the trails. :smirk:

While racing Harescrambles, I got flats while using the 19" on my YZF. When I re-laced it to a 18", I never got another flat. Your results may vary, as I'm a hammerhead when it comes to rock gardens. Maniac

In terms of the width issue at the rear, I've been told that a 110 width helps turning and staying/getting into ruts etc, while the wider 120 is better for desert racing - just what I've been told.

I've tried both and for my ability - punter - I couldn't tell the difference.
