The MXV4 and the MXM4 are both Micheline Energy Tires. The MXM4's seem to appear as the tire sizing escalates above 16 inches in diametre. The below photo is a MXV4 Energy off a New Beetle 2006. The tread pattern is exactly the same as the MXM4 version provided in my above link.bigdogdan2 said:How can you tell these are LRR tires?
