[wheelie good]

Will need to buy some new tyres in the next few months so just checking my car was fitted with the right ones when I got it.

Its a 2009 335i M Sport Highline model(pre-LCI)

It currently got on now:-

Bridgestone Potenza RE-050A run flat tyres

Front

225/35 R19 88Y

Rear

255/30 R19 91Y

Are these the correct types/numbers for my car please?

Was looking to stay run flat but go Pirelli P Zero's tyres

On black circle I can enter

Front

225/35 R19 but just Y and not 88Y, what's the 88Y mean vs say just Y?

Price is around £210 fitted

Rear

255/30 R19 but just Y and not 91Y, what's the 91Y mean vs say just Y?

Price is around £280 fitted

Thanks in advance

That's the correct size.
91-load index
Y-speed index
