Transamerica Tire Co. Ltd. has added two sizes to its Venom Power brand Swampthing A/T tire.  

 The Swampthing A/T tire is now available in two popular all-terrain sizes, 37X11.50R18LT and 35X11.50R20LT. These new sizes cater to a wide range of lifted trucks and SUVs seeking on- and off-road performance. 

The Venom Power Swampthing A/T features a unique tread pattern for minimal road noise, grip off-road and more.  

The tire is also available in a 12-ply construction for vehicles requiring higher load ratings. 

The newly added 37X11.50R18LT size is popular for some trucks and SUVs with significant suspension lifts – usually three to six inches or more. 

The 35X11.50R20LT size is frequently used on leveled or mildly lifted – around two to four inches – trucks and SUVs.  

 According to Transamerica Tire officials, the 11.50-inch width in both these new sizes offers several benefits for truck and SUV owners. Compared to wider tires, the 11.50-inch width can lead to reduced rubbing against suspension components and the vehicle body, more precise on-road handling, and the potential for improved fuel efficiency. 

The Venom Power Swampthing A/T in these new sizes will be covered by the existing 55,000-mile limited treadwear warranty for sizes 22 inches and smaller.  

The new 37X11.50R18LT and 35X11.50R20LT sizes are available now through authorized Venom Power retailers nationwide.
