Tyres/wheels sizing and types question

Hi all ,

Dam i am posting a lot on this fourm,

Anyway so i recently purchased a trek 4300 ( 2011 model with disc brakes)
some related specs are.

Wheels
Formula DC20 alloy front hub, Shimano M475 alloy rear hub; Bontrager AT-850 disc 32-hole rims
Tyres
Bontrager XR2, wire bead, 26x2.1"


So at the suggestion of a few friends and other riders, I want to change my tires to something A) more road friendly and B) tougher .

There is a lot of glass around , i pulled large chunk of green glass from my Tyre this morning ( green glass on the grass is not fair )

So my question is do the spec have to match exactly like i see a lot of tires that are 26x1.9 or 26x1.5 would they be OK ?

Sorry if this is a dumb question but rather ask you guys and feel dumb here than spend 100 bucks and feel dumb then .


Regards
Tergal

One on my SS bikes is like this. I took an older Stumpjumper and made it a SS road bike with 1.5 tires. The rims I used are for a newer bike that had 2.1 tires.

The link says the tyre is not available.

Some tyres have a wire bead, in other tyres, the bead is made of kevlar or some other flexible, plastic-like material, whcih enables the tyre to be folded so carrying a spare one on the bike is much, much easier.

Folding tyres are slightly more difficult to mount on rims because they tend to flop around a bit.

I've used Innova tyres from Torpedo7 in New Zealand for commuting on an old MTB over smooth and rough gravel roads. Here is a link:

T7 often has these discounted to $9 each, and I'll order four of them at once. Postage is pretty cheap and time to delivery is about a week.

I like Conti Sport Contacts, 26x1.6 (wire bead) and Vittoria Randonneur Pro 26x1.5 (Kevlar bead). Both are in the 500-520 gm. weight range. The Sport Contacts are also available as 26x1.3 for the more sporting minded.

i ended up getting a set of these, they where delivered today, but i noticed i only have tubes around the 1.9--2.1 and they are 1.75, so i will pick up some tubes for them once the public holidays are over.

forgot to update sorry

Been riding on the new tires for 2 weeks now and i love them .

They handle better and seem a lot more resistant to punctures ( touch wood) than the older ones i had.

also seem to cut my ride time down a little bit

Tires with folding beads are usually much lighter.

Road friendly and tougher would suggest the Schwalbe Marathon range to me. They do a Plus which has about half an inch of plastic lining the tyre. I've pulled inch-long thorns out of mine that didn't puncture.

The downsides of the Plus - they are much harder to put on and take off and they make the ride harsher. As a heavier rider that might have an unpleasant impact on your spokes. Alternatively when my rear tyre wore out on my MTB I put a Marathon Extreme on it, which has a more aggressive tread pattern that still works fine on the road but gives more traction when it gets a bit muddy. It doesn't have the thick plastic lining but still seems pretty robust - the web site talks about a ceramic puncture protection layer.

I also like the Extreme because it makes a nice humming noise when you get up to speed.

Your rims may have limits as to how wide/narrow a tyre they can take although I'd expect there to be a degree of flexibility regarding exactly how wide a tyre you can mount.

I have a 1.5 slick tire on my wheel right now (normally has a 2.2 on it for trail riding) because I am using it on a trainer, other than it looking a bit.. how do I say? small it works/fits great.

Consider a panaracer pasela, they have a much better ride than most "sheided tires as the sidwalls flexible not stiiff, and they corner pretty well too! and cost around $40 ea as far as size goes do what you want, just make sure the tires are at least slilghty wider than your rim to avoid pinch flats and they corner ok

I found the Paselas, in the rain, to have less durable sidewalls than some others. I am sticking with the Conti Sport Contacts for the moment.
