Hello, I would like to buy a set of new winter tires. I decided on GoodYear UltraGrip 7. But now I have seen that there should be the UltraGrip 7+. It should be improved even further. Priced they are actually equally expensive. What would you recommend? I did not find too many reviews for UG7+. It is always praised the UG7. It can also be a slimming improvement? Therefore I would like your tips and advice on this. may also experience. Thank you very much in advance. mfg, wynie
