plus sizing- add 10 to the width and minus 5 from the sidewall % when increasing each rim size
You can get away with deviating a little from this but these are the best measurements for the SRT
I think a 17x7 or 18x7.5 is fine- any good tire should should be able to help you out more - so will the search button
Its really tough to say what will fit. I got a 2nd set of rims. 17x7 rims w/42mm offset. the Spokes of the rims hit my brake calipers. 3mm spacers still didnt work. Im going with 5mm universal spacers.
I did a search on these rims. REV Model II . A site says they fit an SRT4. With spacers. lol!
depnds on the off set- I believe the SRT needs 45 or 48mm offset to fit correctly and cover the calipers
Do the research befor you buy! I know of a couple people who got rims then found out they didn't cover the caliper correctly
