RV FEATURE
RV tyres aren ’ t cheap , nor are they something that should be taken for granted . So how do you choose what ’ s right for your setup ? For starters , it helps if you understand tyre types and markings . Let ’ s look at RV tyres in more detail so you ’ ll be in a better position when making that next RV tyre purchase .
RV WHEELS
Reputable RV manufacturers will use a wheel rim that ’ s designed specifically for RVs or trailers . Unlike the tow vehicle , which distributes its load over four wheels , the tyres on a single-axle RV with two wheels have their work cut out . When you add differing suspension systems into the mix , it soon becomes apparent why not all vehicle wheels would be suitable for an RV . Before fitting any vehicle wheels to your RV , check with the wheel manufacturer to ensure they ’ re suitable for an RV and the large load being placed on them .
RV TYRES
While there aren ’ t tyres available that are specifically manufactured for use on caravans , there are tyres available that are specific to trailers . These tyres come in a range of sizes and configurations , and they ’ re designed to carry heavy loads . With tyres and trailers , the tyre ’ s load-carrying capability forms part of the overall suspension system . The tyre type and its inflation rates will be specified by the RV chassis suspension engineer .
WHAT ’ S DIFFERENT ?
Surprisingly , there are many differences between vehicle tyres and the tyres found on caravans / trailers .
One of these differences is that vehicle tyres have to contend with higher cornering forces and there ’ s a requirement that they be quieter for road noise , too . They ’ re also generally ‘ softer ’ since they ’ re matched with a sophisticated suspension system on the vehicle . However , these tyres also need to meet a specific Noise , Vibration and Hardness rating .
Most RV tyres don ’ t have the luxury of being supported by a suspension system that ’ s of the same sophistication as that found on the tow vehicle . When correctly inflated , there is therefore an expectation that the RV tyre will absorb some of the road ’ s harshness .
In many cases , an RV ’ s tyres aren ’ t subjected to the same kilometres usually travelled by a vehicle ’ s tyres . This means tread wear rates can be low .
