Unser Premium model with 60 ° / 90 ° and new carbon fiber heater 2.0

Extremely fast and even warming of tire and rim with our unique, advanced carbon fiber 2.0 technology. For details, see below under "Description". The already enormous lifetime (> 15 years are not uncommon) increases again.

Asymmetric heating profile: In the sloping area, the proX has an approx. 15% higher heating capacity to ensure sufficient curve grip even with short heating times. The attached by Velcro color "Strip" can be cleaned in case of contamination or can be replaced with a different color request.

Also available as a heat-resistant Vollnomex version, for motorcycles where the exhaust pipe is kept very close to the tire.

Why KLS tire warmers?

KLS Heating technology 2.0


In the model KLS proX-TST Our newly developed carbon fiber heating technology 2.0 is used. So far, our heating fabric consisted only of longitudinal carbon filaments. After very extensive tests we can now offer our "Carbon Fiber Heater 2.0". The carbon threads are now arranged in a kind of lattice structure. Damage to a carbon thread, eg due to mechanical overload, no longer leads to damage or failure of the tire warmer.

The well-known uniformity and rapid warming remains unchanged in Version 2.0. However, the durability and service life is multiplied by this new development. Countless GP winners and world champions rely on our superior heating technology. The fastest possible warming of tire and rim without local overheating on the sensitive tire rubber ensure maximum grip and durability!
Only the proX has an asymmetric heating profile: In the inclined area of the tire, approx. 15% more heat output is produced than in the middle tread area. This ensures that even with short heating times of the inclined area provides sufficient grip.

Another unique feature of the proX: 3-dimensionally preformed heating elements for optimum fit / heat transfer and a long service life.

With the proX-TST you can select two temperature levels by means of a miniature switch. Precision thermostats with ultra-short control hystereses are used. The target temperatures are 60 ° C or 90 ° C. On the one hand, the 60 ° C stage has proven to be ideal for heating very temperature-sensitive tires, eg rain tires or intermediates. On the other hand, it offers the possibility of keeping a tire warm for a long time at a "grip-friendly" temperature level without harmful side effects.

Example: in free practice, the driver comes into the pits and it is still unclear how long the break will be. You can then put the proX-TST on the 60 ° C level directly back on the tires and keep warm, if necessary, longer times of> 1.5 hours.
Approximately 10 minutes before the driver comes back on the track, you switch back to the 90 ° C level to bring the tire to optimal operating temperature,

At 20 ° C ambient temperature approx. 30 minutes at 90 ° C tire temperature and approx. 45 ° C rim temperature.

The proX-TST is equipped with a red and green LED indicator. The red LED indicates the active heating mode (ie red LED = on) or the regulating action of the thermostat (thermostat off = LED off).
The green LED lights up whenever the tire warmer is connected to the power supply.
The advantage is that you can check at a glance (even if the red LED is not lit), whether the function is guaranteed.

Outer material and strip from "SuperTex". Airtight, heat-storing, water-repellent, dirt-repellent, washable!
Inside: The high quality and heat resistant "NOMEX"!

Also available as VOLLNOMEX-VERSION with red, blue or black strip. Inside and outside material here made of high heat resistant NOMEX.
For motorcycles where the exhaust pipe is very close to the tire (approx. <50mm), it is recommended to use the Vollnomex version. Otherwise, it may cause damage to the tire warmer when installing or operating the tire heater with a very hot exhaust pipe.

The sidewalls extend far down the side over the rim flange to protect the sidewalls of the tire and the rim from the cold wind. On the one hand, this improves the suspension properties of the tire and ensures a more constant tire air pressure due to a slightly higher rim temperature.

A central hook-and-loop strap and elastic bands on the side allow quick and easy assembly and disassembly.

For the first fixation on the tire, our tension spring incorporated in the tire warmer (protected by a registered design!) Has proved its worth. The fumbling threading a cross-strap through the rims deleted.

The power supply is via a 1.8m long connection cable with Euro plug.
A stable cable strain relief ensures permanently trouble-free operation.

The basic color of the tire warmer is always black on the proX-TST.
Available stripe colors: black, red, light blue, royal blue, neon green, neon pink, orange, neon yellow, yellow, silver gray, gray.
Sizes: 90-17 ", 120-125-17", 160-165-17 ", 180-190-17", 195-200-17 "," 205-17 "
(Other sizes on request, simply state your tire sizes when ordering.

Any names or logos can be printed. Ideal not only for advertising purposes, but also as anti-theft protection.

Surcharge per set: € 50
