OK, someone has to ask the silly questions, so here goes.
If I do decide to replace the RFTs, on my car the back 2 tyres wear quicker than the front 2 of course, unless they have been rotated. So if I want to replace the back 2 RFTs, do you have to replace all 4, or will 2 RFTs be compatible with 2 normal tyres? I would hate to throw away the 2 good front ones
Would also have to investigate a spare tyre too.
Be kind with the responses
