What a diff. 215/60/15 to 225/50/16...??

[Ajsdream]

The lowdown 215/60/15 Dunlop Sport A2 on factory 97 J30t rims to 225/50/16 Dunlp SP 5000 on factory (Q45 rims). I have put them on for the spring/summer. Does anyone know if the weight diff. is bad for braking? acceleration? The handling and look is awesome!!

I have not weighed the difference between the two yet. The offsets were identical. I also am unsure at the psi level I should maintain?? The car sure feels heavier but feels solid and quiet, even for Z rate tires.

Lastly, the sunroof is sticking at random. What should I regrease/lube with to help it along? I already know if it breaks i am screwed($$$$$).

As always thanks for the replies and info.....

You've gone from a 93 weight rating to a 91, so you will need higher pressures to preserve your load carrying capacity. Looks like you are down about 4%.
