Just purchased 4 x Superia Eco Blue 4x4 SUV 225/55 R18 XL 103XL to replace the original TOYOs. The TOYOs have done 30,000 miles so have done pretty well, but they are vulnerable to nicks and tread damage it seems.
The SUperia Eco Blues were £54 inc VAT each delivered! They have a better wet and dry grip, and nise rating than the TOYOs. Ive never heard of them, but now I've got them ready at home to fit, they look decent enough to me and a very similar tread pattern to other SUV tyres around.
I rang my lease company before the purchase and they confirmed in an email that I can fit any tyres I like onto the leased vehicle, obviously keeping to or exceeding the original tyre specifications.
Reviews (the Superias seem popular in New Zealand and Australia) are good, suggesting long lasting wear characteristics too. At £54 a corner I am happy to give them a go! My local stealer wanted £200 per tyre to replace the originals with replacement TOYO R37s - they must think their customers were born yesterday.
