tires

Welcome aboard.

Yep. Some.

Some time in either the wheels and Tires forum, or maybe the 2nd gen forum, will find days of reading on tires.

But these aren't really MPG getters regardless. Some are just worse than others.

 

Your gear ratio is now about 3.95 instead of 4.10, at least while the tires are new. The tires should be 5-10 lbs each heavier depending on the exact tire.

They are an inch taller and wider than what came on it. You're speedometer will read about 2-3 mph slower when at 70 mph when the tires are new. But by the time they have 40,000 miles on them and the tread has worn down they will be the same size as the factory tires when they were new.

In theory you should see a small loss of power and fuel economy, but in practice not enough to notice. I've been using that size and type of tire on mine for years without any measurable loss of performance or fuel mileage. The lower axle ratio that comes with the 4 cyl engines probably does more to offset any potential problems than the 3.73's that come with the 4.0 engine.

 

Welcome to TW! Those are only slightly larger than factory 265/70R16 tires so any effect will be small.
