Does anyone know if there is a tyre size I can run on my B310 for 15" wheels that won't mess with the original speedo? I have to get 15" wheels so my only other option is to get the speedo re-adjusted = big waste of money -_-

go and talk to gary, he will know and will have the tyre charts to sort it out etc

is your goal to maintain the current level of inaccuracy or calculate the size you'd need to make it right. you can workout the % increase need using a GPS

Had a yarn to Gary and he said there would be a low profile tyre that would sort this out for me just a matter of shilling out the massive amounts it costs for them haha. I'm not sure if the speedo is out atm because the previous owner f****ed it or because of the tyres that are on it now. Either way will have to sort something out soonish before I commit to a large sum of money being spent!

According to the internet the factory tyre is a 175 - R13 (which is approximately a 80 aspect rtatio sidewall, so 175/80R13).

A 195/50R15 tyre is almost the exact same size (overall diamter), within 1%. They are readily available, tradme prices start from $90 new.
