Anyone know if these tires fit the Bullet? If you are running them how do they rate?

4.10 x 19  is the low profile equivalent of  3.50x19  so it should fit.  ( though there is apparently some issue about WM2 versus WM3 rims )


Here is the tire thread:

I wouldn't count on it fitting.
It might, but it would be close.

If you want a good tire, try the Avon AM26 Roadriders.

     I have touted the AM26 's before. That 4.10 Dunlop is too wide. In tire speak 4.10 indicates a 4 inch wide tire with a 90% aspect ratio, so the height is 90% of 4 inches = 3.6 inches. It is just a little too wide and high. The AM26 100/90-19 is 3.9 inches with a 90% aspect =3.5 inches. It doesn't sound like much of a difference, but it is enough.

I have the Dunlop K-70's front & rear...3.25 front...3.5 rear...IMHO (and that ain't much at times)...that plenty of tread on the tarmac. They replaced AVON Speedmasters that were OEM and looking a bit dry rotted.  Its all good

Bartlett runs these on his bike:
"I replaced the stock tires with bigger 4.00x19 Duro #308 Universal last summer. Not only do they look cool, but they're a lot more forgiving on uneven pavement. I ride 50 miles round trip to and from work every day it's not freezing and raining. The Enfield rides very smooth and I love the rumble of this single thumper."
This is a quote from his blog, Her Majesty's Thunder, the blog post was March 2, 2010.

I run the K70's also. They are a great tire. IMHO they look and perform much better than the Avons. I would recommend them to anyone wanting to keep the vintage look with some additional performance.

A skinny tire up front is recommended if you want to keep the handling characteristics of your Bullet intact. A fat tire up front might look cool but will definitely change the handling for the worse. Some see the sacrifice worth it to obtain a certain look but I personally think it is crazy to change anything that would sacrifice the handling characteristics of a Bullet when handling is one of the best attributes this underpowered machine has.

running a K-70 4 by 19 on the rear and a 3.50 on the front. Very tight fit with the K-70. I personally have not noticed any loss of handling with the wider front tire here in the Ozarks. Once I got the kickstand legs ground down on the curves it was all good. With the 4 by 19 you get more ground clearance and the stand feet don't scrape the pavement in turns.

Where did you find a 4 X 19 K70?  I've only seen the 3.25 & 3.50 X 19. Joe

Joe, there is no 4.00-19 K70. Stay with the stock sizes 3.25 and 3.50, any alteration will do no good.  Furthermore, the K70 is ridicolously cheap in the US, you may get them for about 65USD. Regards

Stationed in your wonderful country in the 70's near Wiesbaden. Finthen Army Airfield. Loved it over there. Been thinking about these 4.10X19's in the N.C. mountains. Joe
