Need to replace rear tyres, prefer to stick with uniroyal. Incorrectly fitted 175/65 standard tyres about 8 years ago but need higher load tyres even though camper is basically day van. What size in 15 inch as can only find 195/50 in Xl and wanted same 65 profile as before have people fitted. Engine is only standard 1600
Yokohama do a 195/65/15 in XL rating (98), I’ve got some on our westy at the mo. Got em from black circles
The closest to standard diameter in a 15” is 195/70, these have a high enough load rating: https://www.mytyres.co.uk/rshop/Tyres/Uniroyal/Rain-Max/195-70-R15-97T-RF/451927
Or these in 65 section if you want a smaller overall diameter. https://www.mytyres.co.uk/rshop/Tyres/Uniroyal/RainExpert-3/195-65-R15-95T-XL/R-271156
