Threw on some 285s today.

Finally pulled the trigger on new tires today.  Went from the factory 265/65/18s to 285/65/18 Yokohama Geolandar X-AT.  My son got them at his shop at a great price.

 

Great fit on the stock 18s with a Rough Country level.

Side by side comparison of the factory vs the Yokohamas

Looks good, did you have to tune for the speed sensors?

[BamaBen]

GPS shows 51 mph at 50 mph speedometer indicated.  I can live with that.

Surprised it's not a bigger difference.

How was it reading before?  Was it spot on?

Bigger tires than factory should mean that you're actually driving faster than reported on the cluster, isn't that right?

These tires are the same height as stock so speedo should be really close. They are just wider then the stock.

Good look and I like the 285s on the truck. 

Currently running 275 55 20 from my sold off 2003 Sierra Denali. I couldn't let go of my forged Centerline Tomahawks.

 

Originally had 275 60 20, which went to the SD and think I'll be going back to a 285 60 20, if my Nitto 420s ever wear out.

The Yokos are 1” taller than the 265 Wranglers, at least to the calculator below.  Speed difference varies as speed increases.

[BlaineBug]

Close enough!

Looks good...definitely a bit more aggressive looking!

 

How do they sound out on the road?

[BamaBen]

Not too loud.  Definitely not as loud as a pure mud tire, but just slightly louder than BFG KO2s.  They may quiet down after a few miles to break them in.

 

I will say they have a stiff sidewall.  Much harder feel going over speed bumps at 33 psi.  Could be that my Wranglers were wore out too.

How did it effect your fuel economy?

[BamaBen]

So far avg says about 1 mpg less.  Given the speedo is off about 1 mph, that could be the reason.

 

Honestly, I haven't driven but about 50 miles since I put them on.  Chillin and grillin all weekend.  Back to the grind tomorrow so I'll get a good sense on in town mpg this week.

Appreciate the feedback & interested to hear more as you put some miles on them!

So after 3 days of regular mixed driving about town...some interstate, some downtown, lots of 55-65 mph stop and go  highways...I've averaged 15 mpg.  The Toyos are heavier than the little Wranglers I took off, so I guess it should be expected.  I won't know long trip mpg until next month when I have to drive to Orlando.
