Hi:
This is Louis Campodonico and I represent Achieva Rubber Corp. we are the USA distributor for Innova tires and tubes. We are concerned about any technical problems that people may have experienced while using our product and would like to address some of these issues.
First and foremost is that Innova Studded Tires are designed to be ridden on snow and Ice.
We offer tires in 26 x 2.10 with 268 studs and 26x1.90 with 104 studs, 700C x 35 and 700Cx38 with 144 studs, as well as 20x2.125 and 20x 1.75 with 144 studs that are designed for recreational use on snow and Ice. If you ride on pavement and the studs come out or are worn out then we recommend that you replace them as necessary and offer a stud kit with insertion tool and 20 studs or you can buy a bag of 100 studs without the tool. The cost of these items is very affordable and available thru your local bike shop; they can order the kits or extra studs thru the wholesaler Q B P or directly from us at Achieva Rubber Corp. (310)328-8868 and ask for Lou.
We ask that people who use our studded tires on pavement periodically inspect them for wear and replace the studs as necessary. Also the latest batch of tires that we received from our factory has a new rubber compound and the studs are harder to remove. You are buying a high quality product at a great price that is intended for use on snow and ice; and if you ride on pavement to inspect the tires periodically for worn out studs and that a stud replacement kit is available.
I Hope that you can enjoy winter snow and fun on ice while riding the affordable alternative “INNOVA Tires”. :)

Sincerely, Louis Campodonico
Achieva Rubber Corp.
