Advice needed please. Will VRX CJ Lancer 18 inch rims bolt straight on to my TW Magna VRX/AWD.
Is this a good move or a bad move? I currently have 17 inch rims.
Thanks in advance for any advice.

I've seen it done before on here a number of times, on TJ's-TW's it looks good. I dont know of anything bad that can occur from it beside from steering inaccuracy from first fitment but an alignment & balance will fix that

You will need to put new rubber on the Lancer rims. As they will not be the correct load rating for a magna.

They will be fine, I run 19x8.5 with no issues. Your only issue, like above will be correct rubber.

225/45R18 tyres should work well on those rims, and there are some good options in that size though they tend to be on the expensive side as it isn't as common as some other sizes.
