This question is not for my G but the answer should be roughly the same for any car, I believe:

Does it matter if I take a 235-55-20 oem tire and replace it with a 245-55-20 or a 245-50-20? Hoping to plug and play. THis is for the wifes 09 Murano LE. Tires in OEM dimensiona are expensive and rare.

Thanks for the help!

 

this should help you decide - enter the sizes and see how they compare:

^ that link should give you the answer you're looking for. less than 3% difference should be fine. The lower the better. And if the vehicle is AWD, you'll want to have all four the same size.

 

Mucho gratitude

 

245-50-20 is the way to go - saved 200 per tire LOL
