Manchester, CT | Fellow Riders
As I read through the thread on Cobra tires the message is loud and clear that tracking and specific psi ranges are very important. I would like to get feedback/suggestions for which tire pressure gauge to purchase.
Any and all input is greatly appreciated! |

, IA | Roadgear digital tire gauges $25.00 works great |

New Mexico | I use the Doran TPMS. It has an accuracy of +/- 1.5psi, which is good enough for me.

| I check my tires often and have found the Roadgear Digital gauge to work best for me...Seem to be fairly accurate compared to others I have used..No real way to know I suppose but it does it for me.... |

Westchester Co., NY | I also use the Doran. Seems pretty accurate. But it can take up to 6 minutes to get a reading after starting the bike or turning the key to accessory. I just use that time to get all my stuff together. |

I have mine wired in directly at the battery so no 6 min lag.

| Just checked out the Doran TPMS, 12.5 % accuracy, isn't that 4 or 5 pounds in our tire pressure ranges? I sure like the idea of not having to get down on these creaky old knees any more than necessary not to mention finding the valve stems on the rear tire.

Peru, IN | I agree it's a PITA to find the valve stem on the rear wheel. I'm blessed that I have a garage so when I get home (or before I leave out), I can roll the bike a bit then lay on the ground. You probably don't need to check them more than about once a week anyway.
I use my Progressive (zero loss) air pressure gauge. I try to keep my tires as close to 40F/42R as I can. (Always assuming the gauge is correct, I'm at 39.5F/41.5R as of this afternoon (and 36 pounds in the shock...yup, I'm a fatass)). I carry the Progressive gauge in the saddlebag all the time so only having one gauge means I won't lose one.

| Been thinking of ways to find that rear stem, maybe a small mirror propped up on the floor and a mark on the rim. Getting ready for a ride down to the Tail of the Dragon in June and I'd like a repeatable way to measure the tire pressure. The Doran TPMS is 200 bucks and that's the better part of a killer tune.

| being old I put a mark on the side of the rim. Check the first of every month and when it gets in the mid 90's and above ever two weeks

I read the +/- 1.5 spec here: Sensor Pressure Range. Am I reading it wrong?

| You are reading it right. I called them and the tech said +/-2 psi as the max deviation.

Do you top it off with the hand pump as well? Seems like that would be a lot of pumping if you had to pick up 3 or 4 pounds.

| Your reading it right, I hadn't read far enough. You can manually check the pressure using the monitor and it is within 1.5 pounds but the alarm is what is at 12.5%. It's a very nice feature and I'll be picking up beer cans on the side of the road to buy one. |

I tried pumping up a tire with the shock pump once. Just once. I just use it to check the tires. If they need air, I'll take it to the air pump at the gas station. |

Manchester, CT | So Monkeyman your Doran system is quite accurate. Another way To say it is....across the entire range/ spectrum of the psi rating which is 10 to 87, the accuracy will be within +/- 1.5 psi. It does not mean for example if the psi is 40 that this number could be +/- 1.5 psi e.g. 38.5/41.5 |

| That's exactly what it means, Tom. 38.5-41.5. I've found it to be very consistent, though. It seems to maintain the same deviation. In other words, my front reads 1 pound high and the rear is dead on compared to my road gear gauge. Each time I check and compare them the deviation is the same.
