Standard tyre size for original 15 inch BBS x-spokes is 205-55 R15.

Standard tyre size is 205/55/15 as stated.

The 205/50/15 apparently improve feel but of course your speedo will be slightly (more!) inaccurate.

On a lowered car I'd go for the 50s as the 55s can look a bit balloon-like.

Thanks for the advice guys will go with , 205/50s thinkind dunlop at moment

Goodyear F1 would be a nice bet

205/50x15 is a standard Cossie size, so you shouldn't have too much trouble getting some decent tyres in that size..
The 55's may look a bit too swollen as Zayyan says
