I would be most grateful if anyone could tell me if a 4-stud 195 50 r-15h wheel would fit on a yaris t-sport with 4-stud 185 55 15 alloys. Im quite confused about these offsets/fitments etc. Thanks for any feedback, would much appreciate it as ive seen some alloys on ebay, but odviously want to make sure they fit on my pride and joy. Cheers

Depends on what the PDC is on the 4 stud wheels.. the Yaris is 4x100. The 195/50x15 Tyres should fit without any problems, but this really depends on the offset (thats the ET number) of the wheel.. Yaris offset is ET35 - ET45.. Ideally an offset of ET38 - ET 42 would be best.. but if you are lowering the car.. 195/45x15 would be advisable.

Post the link to the wheels you have seen... might help to answer your question.
