I'm looking into a set of Rota P45R's, 18X9.5 +20. Not sure on the tire size...probably 245s, not positive. I was wondering if any one who has them or is good with wheels could tell me if I might have any fitment issues on stock suspension? or lowered on swift spec r's? Will I need to roll the fenders or need spacers at all?

I'm trying my best to learn about wheels and offsets, it's just hard to predict these things I suppose.

 

Also, just found this in the p45r thread

Now would +20 be worse or better than +25 in terms of fitment? Would I need a bigger spacer, etc?

 

245 width is almost the stock size. Why would you run a stock size tire on a wheel that is 1.5inches wider? You can run 265s on those wheels.

 

Like I said I'm not sure on the tire size, they're used and the guy hasn't answered me on tire sizes...so...

 

Sir

Continue your research until you know exactly what youre getting into. IMO, any low wheel offset +30 and below will probably require some level of rear fender roll & even a pull depending on tire size.
Look at this pic. If your wheel/tire pkg cannot float into the well then it doesn't fit.

I read & heard guys say, "Well it only rubs when I have a passenger or hit large dips" That kind of mind set is not right

Joe BTW, That pic shows a +29 wheel w/ a 275 tire

 

Not hard to predict. It's just maths.

Amirite?

OEM is 17x8 +38 235/45R17

 

That is seriously cool. Thanks for this!

And that baby cracked me up

 

They're 255/35/18...

From that program it seems like it would fit with possible rear rolling, and definitely spacers for the front brakes

 

+20 is not a good offset. I would look at 35 (or if you have to +30).

 

you are going to need to roll your fenders and possibly even pull them a bit.
