front 23c tyres with rear 26c tyres

Hi,

I would like to ask a question of using 23c and 26c tyres at the same time, would there be a problem? Because my cycleops trainer burns my rear tyre so much with black particulars everywhere. I will replace it with a minoura DUALIST tyre which is 23c.
While my current front tyre is 26c

Many thanks!

No problem with that. People often use 2 different sizes on the road too, to achieve various results. A bigger tire on the rear is nice for added comfort. A knobby tire on the front and a smoother tire on the rear can be good for a bike that sees trail and pavement use.

thanks for the reply,

actually I am using a Road bike which has 26c tyres, the 23c dualist tyre is to replace my rear tyre for the trainer so that it wont burn so bad.

SO I will have a smaller tyre in the rear... Would it be instable then? Should i also change the front wheel to 23c or its not necessary? My 26c tyres are new..

No problems at all. I think that fastjake was just giving examples of benefits of using different sized or types of tires.

Correct.

No need to change the front tire, especially on a trainer! You can go as narrow or as wide as you want, on the front or the rear, providing the tires fit within your frame and brakes. This won't work if taken to an extreme as the tire won't mount on the rim properly, but going from 26 to 23 is such a tiny change no problems will result.

thanks, because the other day I asked someone, he said using 23c and 26c together would be dangerous esp. on road bike which goes high speed....

thats a relieve, because I have already spent so much money recently on my bike and accessories...

I just got a Giant SCR1, then cycleops fluid2, clipless shoes and pedals.. sigma bike computer, Fizik seat as the original one is unbearable.... and then my trainer eats my tire.. need a more durable tire...

I run mixed 23s and 26s on the road all the time.

You don't even need to run a front tire at all on a cyclops trainer. If the forward lean bugs you, put a book under your rim

Don't put your bare rim on bare tile, concrete or the like, however.

According to this website you can use your Dualist tire on both the indoor trainer and the outdoor pavement: http://thebikesmiths.com/store/produ...-trainer-tire/

100% false. People use different size tires all the time. For a while my commuter had a knobby 54mm tire on the front and a 38mm slick on the back. Zero problems, even when barreling down hills at +35mph.

After a while running two different tire sizes became old hat, so I graduated to two different wheel sizes ]

This bike handles a lot differently like this but it's not life threatening.

btw, regarding the current inner tires, I can just keep them and switch the outer tires to 23c without a problem? even 20c?

people_atease: Make sure that you are not running the tire underinflated and are not applying too much pressure with the trainer roller. You only need enough roller pressure to keep the tire from slipping. Too much pressure will bend the tire cords at too acute an angle and destroy any tire no matter what tire size you use. You might want to roughen the roller surface with coarse sandpaper or cover it with self-fusing rubber tape for more friction so that you can lower the pressure while avoiding slipping.

Yes. You might have to work a bit more to squeeze the tube into the tire but it won't be a problem. Just make sure it's not folded over itself anywhere. Tubes are pretty flexible.

Again, if you take it to extremes you'll run into problems. If you try putting a 35mm tube into a 20mm it probably won't fit. If you use a 20mm tube in a 40mm tire it will be too narrow and won't inflate the entire tire, causing really bad ride and handling. Putting a big tube into a small tire is better than doing the opposite.

A 20mm tube will have no trouble at all expanding large enough to fill a 40mm or even larger tire. It'll be stretched rather thin and will therefore be more permeable to air than usual (i.e. require more frequent pumping to maintain full pressure).

Note to OP: tire widths are given in mm, there's no reason to put a "c" after them.

thanks for the tips, you can see from the attached images, my rear tire is like that after the first 30mins trainer use... terrible... I had to sweep the floor afterwards..

thats my kenda tires

Why not get a trainer-specific tire while you're at it?

When I raced in the early 70s, it was common to run a thinner or harder tire in the front in crits for the supposed quicker turn in.

THis is a good suggestion. A few companies, Continental and others, I think, make these tires which are not good to ride on the road but last longer and shed less reidue than standard black road tires.

true, but I dont have an extra set of cassette and wheel so it would be painful to change the tire everytime i go out.... thats why i bought the dualist to give it a try

It's worth saying, I have a bike with a 35 mm tube in a 60mm tire on the front, and a 35mm tube in a 35mm tire on the back. The only problem; now I have a sloping top tube.

Replaced the rear tire with the newly bought minoura dualist tire.. tried on the road, it feels the same!

but I found out there is a thin layer of glue on the surface/ side of the Dualist tire. How could i remove it? With WD-40? or glue remover? I am afraid the chemical would damage the tire...

thanks

It's a mold release agent. Don't really need to remove it but if you want to a sponge with warm water ought to take care of it. Maybe some Dawn hand-dishwashing liquid if needed.

It will wear off as you ride.
