Are they for tubeless only?

Would you get the same effect with frozen petits pois?

Iv seen them before, not heard of any issues with them and saves having ugly rim weights on.

Grouch, they're for tubeless only, theres no chance getting them in an inner tube!

That company's webmaster needs to install a spell-checker!!

since spell checkers are now common place my spelling has gone really bad. Not good in a school!

wrong, if you read the q's there is an applicator to get them in tubes.

I worked in a tire shop years ago and seen first hand what they do to the inside of a tire,wear from the inside is not a good thing you cant see it , they break down the tire. I would stay clear for bike use.

For the first 100 yards then they will have to be called mushy peas.
