Hey peeps, I know this topic has been discussed before (many times) but searching doesn't give me an answer.


My project is getting close to being "Road" tested now,started first time surprisingly. 😁
I currently have Michelin ac10's on the bike but don't fancy testing with those over the autumn/winter months. As I've not riden a bike for a decade, commonsense says get to the hang of it again on private land I can access legally, and then break in the engine/test with some road miles.
I've also never riden off road so it feels like the right way to go, just want to make sure it's reliable.

I'm looking at road biased tyres, I've seen some IRC GP-1 at a good price, decent reviews but not in England. Another option is the Michelin Sirac possibly. I'm looking for suggestions not only on tyre but sizing too.

I have standard sprockets and a 120 link chain which I can't use with the ac10 as they are a 120 width. They were cheap(brand new) off a friend and meant I could roll the bike around the garage.. Haa.
I could buy a longer chain I suppose but I'm thinking I can fit those tyres when it has stretched enough.

Thoughts please?

Michael.

Lots of opinions on tires here: http://www.xt225.com/forums/ubbthreads.php?ubb=showflat&Number=40864

A standard 50/50 tire will work fine on the road.... IRC GP-1, Kenda K270, Shinko 244... they're all about the same. Just be careful on new tires until they get broken in. They can be pretty slick on the street for the first 100 miles or so.

Chains don't stretch, they wear. If the tire won't fit now, I sure wouldn't want to use a chain that's worn so much that it would fit.

Thanks peejman.

The 120 tyre I have on now means the adjuster is on number 7 to get clearance.

I'll take on board about the chain though.

Would I be right in thinking a 110 will allow enough clearance to push the axle all the way forward?

I remember getting new tyres on my fireblade many years ago, they took a little scrubbing in.

Can't really say on tire sizes with knobbies. The actual diameter and width vary a huge amount in the same size. Some tire manufacturers public actual sizes for their tires, some don't.

I rode sport bikes for about 15 years. Never, ever use a new tire in the wet.

You could try a 14T front sprocket to gain a bit of chain room.

I think I'll get these IRC GP-1 and see how much room I have. £89.99 for the pair on eBay and I've just received a 10% off code....seems like a bargain to me.

Currently I have one of these on the front, and a Bridgestone Trail Wing 302 on the back. The GP-1 feels like it will last forever and never wear out, the 302 might not even make it to the end of the year.

Hi Cloud,

I normally run TW301 and 302's on my bikes and usually get around 10,000 miles from each. The odd thing is that on my 250's, the front's wear out before the rear.

The fronts wear out on my 225 before the rear.

Well the GP-1 are on the way, I go on holiday Wednesday so I'll have to fit them when I return. I'll update as to how they fit.
Hopefully my new choke plunger will be machined by then too, a friend is making one for me as mine is goosed.
