I have a 2017 JK with Terra Flex level kit. what is the widest tire I can fit on this rim 16x8?

ScottH

  • Thank you for your question! You would be able to fit up to a 12.50 inch wide tire on this wheel. I would not recommend exceeding 33" of height for the lift that you have.

    Great product. Gives the look I was wanting

    These rims were the perfect fit for my wrangler sport. I put a set of 285/75r16 on them and have had no rubbing while turning. Flexing without a lift I do rub but hence the no lift. Awesome product and great look!

    Mammoth Charcoal with Anvil Wrangler

    Awesome finish, great price. -6mm offset gives plenty of room for the 35/12.5/17 tires without any rubbing on the fender wells. The simple design really adds to the look of the vehicle and doesn't draw attention away from the overall vehicle. Fits like it could have come straight from the factory.

    Very sharp looking wheel. They are just the look I was aiming for on my build. The charcoal gray is a great contrast to my white and black JK. They look fantastic with the 35" tires.

    WOW

    I own a 2014 Anvil unlimited and all I can say is WOW! I had a hard time deciding between the silver and the charcoal but ultimately went with the charcoal in the end and I'm definitely glad I did, the wheels look great with the anvil paint color and the Mickey Thompson MTZ's. The finish on the wheels seems to be Pretty durable. I really don't have anything bad to say about them and would highly recommend them to anyone.

    Lover the look

    I was looking for a classic five star look, but did not like the prices and limited sizes from other sites. I chose the gunmetal because sometimes I think black gets obscured by the tires. I paid $119 a piece and was able to us a $10 coupon code. I am running 295/75R/16 for a tire with a 2.5 lift and a with these wheels I achieved the look I was going for. I was shipped one wheel without a centercap, but Extreme Terrain sent one out immediatly.

    Good Wheel with Some Imperfections

    If you've read other reviews then you know this is a great looking wheel and the offset if perfect for the Jeep. Some reviews mention they got one or two wheels with a small gouge in the lip. I got one of those in my black ones. It's small enough that doesn't warrant a return and it's didn't affect mounting but it just makes the lip look out of round. Other than that the wheels are good.
