Will 20" rims fit under a 2005 grand voyager

 

Depends on the tire.

 

Right if your on 215/65 16inch you can use 225/40 20inch on a 20 inch wheel, which will only give you a discrepancy of only 2mm bigger in diameter. 686mm former, 688mm 20incher. Try etyre.co.uk/tyre-size-calculator for others. Don't know about wheel lock fouling though. Would certainly look good.

 

thats exactly what tyres are on the wheels im looking at .. ... thats my biggest concern the wheel lock and rubbing

 

There's a set of Lenos's here, that increase will however exceed the 2.5% rolling radius rule so you would have to calc the benefit from low profile boots improving the rolling radius.
