The question came up again over the Alberta Shoot Out Weekend why we changed from Mojo that lasted a lot longer (maybe all season in 4-stroke) to the MaxOne by Vega.

The decision was made at club meetings in the offseason after much discussion and posting on the website. While testing showed faster laptimes and good longevity at the end of the day there was also no practical alternative.

The new Rotax Max organizer for North America was not bringing in the Mojo in any quantity - nor could anything else be sourced in bulk (i.e at a good price point) other than the Vegas.

So for spec tire classes the MaxOne tire was effectively the only choice. Anything else would likely be more expensive still.

And they are nice to drive once you have the set up

Some other factors that came into play that were also issues in other regions, was the cost of the Mojo tire had risen to $313 a set and provided marginal performance compared to other kart tire manufacturers.

So far, I am on the same set of tires that I started with at the beginning of the season which includes 3 race days and 2 practice days. My Rotax kart tires probably have one more raceday left in them which is comparable to the Mojo's. This was also during the learning curve with these tires which included running at too high a pressure and incorrect caster/camber settings that probably caused extra wear and tear.

My Briggs kart still has very good tire depth dots and should go at least 2 to 3 more race days.

The Vega tire has a much softer sidewall than the Mojo and a rounder profile which needs a different chassis set-up.
