Much like you wont find tyres that look fit for greenlaning for an r6 you wont find tyres that look like road tyres for a 21" front wheel.

 Yes, you will, Hardly Movinson's have 21" wheels, there's a few road tyres available in 21

I've got 21 inch wheels front and back on my old trailer.

Hehe!

The replacement rear tyre I bought in January 2009 cost me £32.27 and is 300x21, the same as the front.

I must admit that 21 inch tyres are not easy to find but Avon do one called Distanzia which is for the front of a trailie type modern bike.

This is the actual tyre markings chart.

Correction Adam, Avon said the sizes, I merely copied and pasted.

Your front tyre is 90 wide = 90 mm
Your rear tyre is 4.60 wide = 4.6 inches
These are logical sizes shown on your tyres and can be checked with a ruler.

In the Avon Distanzia sizing 3.00 wide front = 3 inches
120 wide rear = 120 mm
These are what Avon recommend for a Serow 225

If you look up the original Serow wheel size you can compare the difference/similarity in sizes and make a calculated guesstimate to apply to the TTR sizing.
You can then see if Distanzia tyres come in these guesstimate sizes.
I haven't got the knowledge to tell you what size road tyre YOU need to fit on YOUR TTR.

I can recommend you to Google for answers.
A good start would be here CLICKY THING where you can read and fully digest the wisdom to enable your guess. (There may be American acronyms and spelling)

When you have made your choice and fitted the tyres you then will be able to enlighten us for future information.

I have a pair of Avon Distanzas which came to me on a road-only TTR250 and I will be putting on my project bike as I am not taking that off road.

The front is a 3.00x21 but the back was loaned to Motad (to do the exhaust dyno testing as the trail tyres woudn't work on the rolling road) and I haven't got it back yet to check the size.

You are aware that mixing radials, crossply and bias belted tyres can be illegal?

From the testers manual;

e. a bias belted tyre fitted to the front with a cross-ply tyre fitted to the rear wheel

f. a radial tyre fitted to the front and a cross ply or bias belted tyre fitted to the rear wheel

3.00/21 is a crossply

90/90/21 is a radial

not 100% but i think a 4.60 is bias ply?

hi every one i am going to need a new rear tyre soon even tho its only been on since sept the road seems to eat it as it is a knobley but the front has a trailmax on witch seems to be ok does any one know where i could get a good priced road based rear tyre or a trailmax to match am i right is the tyre size 120/90/18

thanks

Hi Lewis

I have a TTR in at the moment with TKC80 Twinduro tyres fitted and they look quite road orientated with the knobbles quite large and close together. I think 120/90-18 sounds about right.

Does anyone run Avon Distanzias on a TTR? I run them on my Armstrong MT500's, and they're brilliant tyres for the road!

No, but I do run the Distanzias on my 650 Vstrom.  Agree, they are very good on the road, and not too bad on a bit of slippery gravel either.

Hey Dave, take a tape measure with you just to make sure if you are going to go wider, some manufacturers measure from the case and some from the knobs

I ran 12 PSI in the back and 14 front on my last set of off road tyres

You need about 20psi both ends for the tar though, smoothes out the ride a lot

I know that tyre choice is largely down to the individual and where in the World you may be and what conditions your trails are in etc. etc.

Here in the North of Scotland, not famed for its sunshine but for its rain I have tried a range of tyres all with there good points and bad points.

I was a fan of Bridgestone Gritty 660's for a time but I was fitting about 3 rears and one front a year. Each year I cover about 3000 miles off road and a couple of hundred on road. I stopped using them when the man that was selling them to me at a good price shut up shop!

The next tyre was the Michelin comp 4, which was a good tyre grip wise, but wore quickly and was expensive.

I then used some cheap tyres from I don't know where which had a carcase about as thick as a condom. I replaced it before it wore out because of the amount of punctures I was getting,

Neat in line was the Michelin AC10. A good tyre. The only problem I found with it was it was very harsh grip wise when new. It was hard to predict what was going to happen when you were in a soft spot and then found grip. It would hook up and fire you forwards which is great in a race but not very confidence inspiring at 07:00 in the morning in the middle of winter with the rain coming across horizontal Also on the road they were best described as 'interesting'.

On the new bike it came with Dunlop D605/D605F tyres. As the bike had done less than 1500 miles and we have had a very dry few months I thought I would leave them on and get some wear out of them. However it made me look at the conditions I ride in.

Lots of rock which is a nice grippy sandstone  and not a lot of mud. Sand, yes, and a bit of peat here and there. None of the claggy clay you get down South so nothing to clog a tyre like the Dunlops that are on the bike at the moment and it seems to work fine off road and on road.

So my line of thinking at the moment is to fit something like the Dunlops again as they are working well in the current conditions. Perhaps I don't need a full blown knobbly. Why don't I just go with the Dunlops again? Well, price.

I was looking at the Michelin T63 tyres which I think will work well and are a good price. Does anyone use this tyre? How do you find it?

After nine years of riding the old Raid with the selection of tyres listed above I thought I would have a favourite by now! But alas the quest continues!

Any comments gratefully received

Thanks

Peter

I agree, it looks very similar to the 606, very similar spacing and pattern, I'd buy them.

Hi

yes I know another tyre thread... but theres soooo much choice out there! 

looking at replacing my tyres, been considering a mitas co2 for the rear. Mostly mud/dirt/grass/ruts etc. tracks ridden and on tarmac to lanes.

Questions...

1/ Any comments from people with experience of the co2 would be appreciated.

2/ Any other suggestions for tyres suitable for what I ride would be considered.

3/Any suggestions for a good front tyre?

4/ Do any members use a michelin s12 xc front tyre on thier bike? (yes Im aware it is not road legal but i've read some people still use it)

Cheers

Andy

Hi peter

Thanks for the post,I was beginning to think this post was a taboo subject that people are "tyred" :) of talking about, like "which engine oil".

I'll do some research on the T63's you suggest but sounds like your riding conditions are a bit different to what I encounter,seems like most the lanes are mud/clay.

Think I more or less made my mind up now but was just hoping to get some feedback on the co2 from other users.

So I'm leaning towards the mitas co2 on the rear. The front was more of a difficult choice to narrow down, looking at either mitas c19 or michelin enduro comp. 4.

Still keeping an open mind though so suggestions welcomed.

Andy

Thanks Brian 

sort of confirms what I've been reading on other forums, ordered the mitas rear and michelin front from oponeo,£94 the pair.

Andy

In one word - yes - but what rubber are you currently using?

BTW - I made your link work.
