Toyo Open Country A30

Since I'm kind of a tire nerd (previously managed a tire distribution whse) and about to replace my OEM Toyo A30's; I thought I'd chime in here.

Nearly all OEM tires are not an equivalent tire sold in the replacement tire market. The A30 specifically are an OEM version that looks to be a Toyota-spec'd hybrid of the Open Country H/T and Q/T. While the variables of tire wear are extensive, in the case of OEM tires; the largest limiting factor to their longevity is a reduced UTQG rating. Tires (tread type, inflation psi, driving conditions/environment, et al) have a huge impact on gas mileage and I'd encourage anyone wishing to save a few bucks to track their mileage through something like Fuelly (clicking the sig in this reply will get you there).

Where a replacement tire sold on the open market will typically have a UTQG of 600 A/B; the OEM A30 tires on our trucks are only rated at 300 A/B. They are literally spec'd to have only about half the expected life rating of an aftermarket tire (even from the same manufacturer).

2017 TRD Sport - I'm currently at 31k miles and my A30's are only showing between 5 and 6/32nds of tread left and those measurements are uniform across all 4 tires and sipes. They grip okay in the dry but are SKETCHY in the wet. I've had them rotated every 5k miles as recommended and monitor the tire pressure between about 34~38 from cold/static to while driving. Most of my driving is commuting on backcountry roads to/from work with some highway trips in-between. When I go off-road, it's to get to the backside of the farm to inspect the hunting spots and out again. No deflation needed for those doubletrack trails.

Currently I'm looking for replacements and comparing the Toyo Open Country H/T II, A/T II, Nitto Terra Grappler G2, and Yokohama Geolander A/T S in either 265/65R17 or 265/70R17. Best price I've found locally is on the Open Country A/T II but it's really a tick more aggressive than I need. Wouldn't mind having a second set of wheels with those mounted up but believe they'd just occupy some prime real estate in my shop that I'd rather use for something else. I also included the BFG T/A KO2 in OEM size since that's a popular model for some... but WAY too heavy to be a contender for my purposes.

At any rate, I hope this info helps someone else on their search for a replacement tire for the OEM.

 

Good info. I do the same thing when researching new tires.

The Geolandars on hovering around the top of the list.

The Toyos are oddly sketchy in the wet, but worked well in the cold and snow. It is a very weird tire like that.

 

I had my A30s changed at 60k and they were at 5/32 tread depth at that point.

 

My 19 sport mt came with them , got 25 k miles on them and I like them .
Most of my driving is on the highways 75 / 25 hwy to local driving , don’t plan any off roading .
I live in mountainous area lots of s curves , climbs and descends , north east winters have been manageable
It’s a on pavement and highway tire , fairly quiet , with the stout sport suspension and always
In the right gear it corner beautifully ,and tracks like a locomotive .
It’s not an off road tire , nor a first choice for blizzard duty .
