Hi, I have a 2013 Skoda Yeti that cane with after market rims which fit tyre 225/45/18. These are quite low profile and not ideal when we go away. This involves towing a small boat up steep gravel sections. We want to get some gruntier 4wd tyres so am thinking of getting a second set of rims maybe from wrecking yard. Can you recommend what rims for other car make, model and year would be suitable? Any tyre recommendations would also be appreciated. Am in New Zealand if that makes a difference in any of these details. FYI dealer said they only recommend yeti...even though here the importer for skoda does Audi, Porsche and VW as well! Thanks in advance for any constructive feedback.
