Sounds like good sizes, I'd perhaps also go 50 series next time although my 40/45 series haven't even been installed yet. I still like the rears to be slightly wider than the fronts, not just for the old school look but to bring the tyre to fender edge the same amount as the front has a wider track and can be more obvious with some sizes when used all-round. R17 is also my limit on these, it took time to grow on me also, but I also want to see some sidewall and if possible, RWL too!
