Happy 4th of July to you !

2013 Explorer Sport 3.5 AWD ecoboost, love the car and actually bought it at end of lease...

At 70 k miles now and looking at tires - it's the wife's daily driver and she DRIVES it... so tires are in the works...

it currently has 255/50 R20's and have access to some 255/45 R20's from an Audi and was wondering if they would work ?

pretty sure the tires are fine,
just wondering about speedo, ABS, etc ??? Any concerns there ?

Thanks in advance JDA

 

Looks like a 1" difference in diameter. (30 to 29)

Your speedo will be off about 2 mph at 60 mph. (shows 60 but you will be at 58)

Since all 4 would be the same size, ABS, stability control etc should not notice.

Make sure the weight rating is adequate.
