1. Yes, True, Bigger rim will reduce your acceleration and also ur accelerometer will not be that accurate by around 10-20%. but no worries, power still there. max speed still same. the term "not feel as powerful" shud not be used in this case. edit: rarely i see ppl floord their gas on the road to achieve max acceleration. for me acceleration does not come in concept of driving here. come to traffic lite have to stop also.

2. Depends on user. original width of ur tyre is 245 (stil inside body line). your wider tyre 285 will popout abit thus, when drive tru mud - expect mud on ur windows. advantage is ur cornering will be much more stable and rigid.

Conclusion: your car power will not be affected. only your acceleration. tq.
