I need new tires for my 1974 850. I want to order dunlop TT100 ( 4.10 X 19") correct tires for the bike - the same that are on the bike. JC whittany has them for under $100 each. My question is, can a TL (tubeless) version be used with a tube/spoke rim or is there a major difference? Thanks!
 
yes in my country Dunlop only supply 1 type of 410x19 tt100, ok running with tubes.
 
Shop around, prices vary widely for these tires. It's all I run on mine and I search the internet for every option. I got my last set for 65.00 each and I believe I have seen them as high as 140.00. Also JC whitney was bought out by some corporation and a lot of their motorcycle stuff is still on their website, but no longer available. I live about 30 miles from them and can't even get regular cheap 530 moto chain anymore.
 
Thanks for the advice - I ordered from JC Whittany - they have them still for $92.00 and will ship free through Monday. The confusion was that the online description of the tire read " Dunlop TT100 tubless tire". HUH? I called "tech support" and spoke to a very nice polite 20 year old girl who had no clue whaen I explained that TT means tube-type so saying you have a TT100 tubless tire is like selling an round tool for making square holes- it makes no sense. Turns out - it is a TT tire - the web guy ( probably in indonesia) didn't quite get it right. Well, I'll wait and see whta shows up! I t was nice when you could just go to the local bike shop and buy this stuff from someone who knew what the deal was.......
 
Hehe TT = tube type. Thought it was more like Torphy Touring translation.
Anywho a tubeless tire with a tube on unsealed spoked rims has been the standard for last couple decades. Tubeless is a better tire because it can hold air better than tube type and most of that is d/t extra soft layer on bead bump to seal to rim. This is what confused them because there no longer is any difference between tube or tubeless except whether it needs a tube to hold air in rim.

How about the first tire to lap the Isle of Man TT at over 100mpg.
 
Correcto-mundo yet I can't remember exactly what TT stood for in racing events. GT = Grand Turismo I remember, duh.

BTW on this note beside no significant difference to use tubeless on tube rims, there ain't significant difference between tube and tubeless rims either. Tiny extra groove in tubeless rims to help seat the softer bead to seal better is main feature and some have slightly different side slope or edge to help avoid de-riming on low air. Nothing to do with tire staying on fine with normal inflation.
 
In the case of the Isle of Man TT, the TT stands for Tourist Trophy. I think Dunlop named the tyre after they lapped the Isle of Man at 100MPH as mentioned above.

One thing to check ( that probably doesn't matter much ) is that some manufacturers say you have to downgrade the speed rating of the tyre if you use a tube with it.
ie an H rated tyre ( 130 MPH) would be an S rated tyre ( 115 MPH) if you used a tube in it.

Check with Dunlop if that's the case with the TT100
 
Hi Oakland,
are you able to cancel your order & change it to Avon Roadrider tyres.
I have used TT100 tyres from new but just over a year ago I changed to Avon Roadriders.
WOW, what a difference it made to handling. Miles better than TT100's.
The avons dont let the bike wobble when going over white lines or ruts in the road & it leans over more easyly in corners.
Ive got 100/90 -19 front & rear.
They have a more rounded profile than the TT100, like most modern tyres.
Now the handling is more like my modern jap bike.
Changing to these tyres has been the most noticable change for the better ever done to my 750 commando.
Look at previous threads for the Avon tyres & see what others say about them. Better to enjoy the ride than just going for originality.
Norton used to put Avon tyres on their early commandos anyway.
Cheers Don
 
Judging handling is pretty much subjective unless you have a track and timing available. I do agree that the modern tire profiles are an improvement over the TT tire. As for the Avon, it becomes the favorite if you are running a 19" rear. Not much else available in 19" rear. Changing to a 18" rear gives you a much bigger selection of tires. I run Dunlop GT 501s and am very satisfied. Much improved wear over the Avon Super Venoms I used to run.
