LeCont LH 03 J125/S125 11 x 7,1-5

One of the most common tyres on kart tracks in Sweden. A soft tyre that gives good grip on dry surfaces. The rear tyre is used in the J/S125, KZ & OKJ classes

For optimal grip, tyre pressure should be adjusted based on the track's character, the driver's style and air temperature. A good rule of thumb is to start with an air pressure of around 0.8 bar and then adjust up or down depending on the factors above. A high tyre pressure can be beneficial in slightly colder weather, or if you're experiencing a lack of grip on the track, but keep in mind that there are chassis settings you can adjust to get more or less grip depending on what you're after.

The perfect tyre pressure is hard to nail, but if you manage it, you can gain a few tenths.
