Hi Hans,

Firstly, welcome to the Forum.

Dunlop Trials Universal tyre is a very old one. @GrandPaulZ posted in 2010 he could still obtain them but that was twelve years ago, he will confirm whether they are still available.

Regards,

 

I have heard that you can get them in Japan. was wondering if any had made it to the US.

 

Its really hard to find anything in a 19" front tire.

 

Hi Hans,

really hard to find anything in a 19" front tire.

Also look at 90/90-19:-

. The first "90" is width ("section width" not overall width) = about the same overall width as 3.25 in real life (the two are different cross-section measurements so not directly comparable).

. The second "90" is "section height" of the tyre itself expressed as a percentage of the "section width" = in real life, the tyre will be a slightly smaller overall diameter than a 3.25 - is noticeable on road bikes where the fender was made to fit quite close to the original tyre overall diameter; otoh, as your bike's enduro-style, there's quite a gap between tyre and fender normally?

Hth.

Shinko makes a 3.50 x 19" version in their SR241 Series. Revzilla and Chaparral Motorsports carry them.

just wondering how that tire size would perform on a 69 triumph T100 C

 

The Dunlop Geomax MX33 comes in a 100/70-19 front version.

In 73 Yamaha made the 360 Enduro with a 21"front wheel to improve stability, if you are not worried about originality a 21" conversion (rim and mudguard) will give good tyre choice.

 

Hi Peg,

The Dunlop Geomax MX33 comes in a 100/70-19 front version.

You sure you mean "100/70"? Reason I ask is I'm not seeing that either on the Dunlop US site or on the Dunlop Europe site? Otoh, I am seeing "70/100-19" on both sites; i.e. a skinny 70-width with 100% aspect ratio ("100/70" would be a fatter 100-width with a 70% aspect ratio, quite a small overall diameter)?
