Toyo Open Country A/T Questions & Answers

Not sure where you live but most tyre places stock them.

Hi Andy, that 80 psi is an indication of the maximum pressure the tyre can safely take and be driven, but you would be bouncing all over the road, a rule of thumb, is between 35 to 40 psi, depending on your load, and on a cold tyre, as the tyre pressure will show an increase once the tyre has warmed up, also on a dirt road drop to about 28 psi, and on soft sand about 18 psi. The shop has them way too hard unless you have a big load in the back of your pickup.

Thank you for your help.

Pressures too low? Your tow vehicle's tyres shouldn't affect the handling of whatever you are towing though

If it happens at 80kph this is a tell tail sign that the trailer is responding to the natural frequency of the tyres (not there fault it as is the same frequency for all tyres of this size). This is also the frequency/speed that you will feel any out of balance that exists in you tyres. There is probably to much weight in the back of the trailer. If you are not careful this will turn into a death wobble if you throttle-off heading down a hill one day soon. The solution is to to move move weight forward in the trailer.

PS the only way out of a death wobble is to accelerate the vehicle as hard as you can or apply a load to the trainer via the trailer brakes if you have electric bakes ... but you must not use the brakes on the tow vehicle to do is. If you do you brake the vehicle you will apply an excitation input to the swaying trailer and will loose everything very quickly. Applying a load to the trailer brakes only dampens out the natural frequency and stop the wobble ... at least untill you head down the next hill.

Had these fitted to my Holden Rodeo and have had a very bad time. First time over a gravel road a rock went through the tyre I thought they were all terrain. Found out it is a very soft tyre and travelling on highway blew a brand new tyre cause the beads broke inside and after four months heard nothing from their claim company. Have seen a lot around and don't know if im unlucky or its the condition up Nth Qld it don't like have gone Bridgestone Duellers.

Had them on our Nissan Navara d40 (similar to Pathfinder) doing a fair bit of towing our caravan and we got just over 30,000 kms out of them. Hard to believe the claims of 90+,000 out of them

Used them on D40 Navara and clocked up 80K plus before selling the car. Brilliant tyre! Those claiming failure probably should find the reason by looking in the mirror... themselves. My Nav ran 30psi all day everyday when empty front and rear on the bitumen, 20% less on the dirt with 20% less speed - result not one puncture. Bumped back tyres up to 36psi on rare occasions when towing a Kimberley camper and again let 20% of the air out on dirt. It works and the tyres will love you for it. OPAT 2 by Toyo is excellent. Check your placard for reliable pressures for your vehicle on the bitumen, not some random number offered by some well-meaning but clueless person.
