Correct tire size

[cheftay]

I've been doing my research on tires and sizes and just wanted to make sure i'm making the right decision before I purchase them.

For my front tire I'm thinking the Dunlop K81/TT100GP 100/90H19 TL
and For my rear, the Dunlop K81/TT100GP 110/90H18 TL

Does that sound right?

Thanks!

Where are you buying the GPs from? Every place I've looked at in the U.S. carries the TT100, but not the TT100GP. Thanks.

[cheftay]

Wellll...
In my research I guess the thing i overlooked was that I was on an australian site the whole time and now that I double checked, they don't ship to the U.S.

bummmmer!

the site was teammoto.com.au

How do the TT100 compare?

Thanks

From this website:

I asked the following question through the 'Contact Us' link:

"What are the differences between the TT100 tire sold in the United States and the TT100GP tire sold in other countries?"

and got this reply:

"Hi Wade
There will be no difference. They all come out of the same factory to the same specs.

Please note there are 2 versions available in Aust
a. TT100 GP Special soft race comp
b. TT100 / K81 standard compound

It is easy to identify the difference by the description on side wall & the way they are sized

I replied to his message a little while ago and asked if there were any retailers in the U.S. that were selling the TT100GP. I'll post the response when I get it. Thanks.

Dang that's good news.
Bikebandit.com is having a big sale on their TT100's, they dont have the 110/90-18 that I need for my rear tire.

I've got 18" gp's front & back, the rear is a 4.00-18, front is a 90/90 H18
I tried a 4.00 on the front once (I wasn't able to get a 90/90) man the thing was horrible to steer, like a tractor!

Yes, there are some sizing differences between the gp's & the std range. No doubt the road range would last a lot longer than the gp's also!

[cheftay]

dang I can't imagine having a 4.00 in the front.

I would like to get the gp's but i'm gonna look around at other tires too.

I've got a 19" rim in the front and 18" in the back( stock wheels)...
Does it sound like I have the right size in mind: 100/90-19 for the front and 110/90-18 for the back?

[yamaman]

100/90 would be ok, 90/90 will steer better, even 80/90 would be ok!
Yep, rear sounds good to me, a 4.00-18 would be just as good.
Here's a conversion chart

Looks like they might have a 4.00-18 for the rear there!

[cheftay]

Oh sweet!

Do i need to worry about the tires width being too small if i were to go to a 90/90 or even an 80/90 for the fronts?

[yamaman]

I've never tried a 80, I can vouch 100% for a 90/90, no problem!

[cheftay]

Well good deal!

It looks like the TT100's on bikebandit.com aren't available in 90/90-19 but the K70's have a 3.25-19.

The K70s are tube type tires and the TT100's are tubeless... can I do either one?

It'd help if I had my bike near me so I could see what I have on it right now but I'm doing all this research from a hotel room in CO haha...

Thanks!

I take it you were planning on running tubes anyway? But yeah, no problem either way. The only time you really have trouble with tubes is either putting tubes in a radial tyre (DON'T do this without fuuly researching) or people thinking their busted arse old 650 mags are designed for tubeless (many are NOT)

[cheftay]

Hmm okay that makes sense.
I wasn't really planning on running tubes per say, just whatever is best If you know what I mean.

[yamaman]

Well tubes are fine, most on XS's will be running tubes. what rims have you got?
Ultimately tubeless are best, but of course that depends on evrything else!

[cheftay]

The rims are the original spoked wheels.

Front rim size: 1.85Bx19
Rear rim size: 2.15Bx18

[yamaman]

Yep, well you'll be needing tubes anyway then. Spring for a new pair of rustbands while your at it

[cheftay]

Super Duper!

Thanks a lot Yamaman!
