these tyre pressure monitors....

Hi Steve, Go to the top of the page & enter into "Thread find" the thread number 69889 & you will get many & varied opinions. The variation comes from the individual need you need to weigh your need up against the available systems. Hoo Roo & good luck

ISteve,

I have and operate both. Internal tyre units (senstyre) and screw-on type sensors (tyredog). If you're doing highway travel only, either will be fine. If you intend travelling on a dirt road, don't bother with a screw on type. They are very poor performers. If you're doing rough stuff, forget the screw on entirely. They are an incredibly poor option. I have posted this info before (Aug 09). Go any form of internal sensor if you want real time and acurate info while in the bush.

Cheers Mick

Derek on here sells them for a reasonable price.
They are the screw on type.

I have a similar set and they have been fairly good. Have 8 sensors on car and van.

They do show the temp as it builds up and the tyres on the sunny side are usually about 3 deg hotter than the cold side.
Have saved me two tyres so far so have paid for themselves.

One minor prob the ones on the van cut out sometimes due to the amount of metal between the sender and receiver.
Fixed that by buyind a small amplifier that goes at front of van

Seems to have fixed the problem.

We haven't got ours yet, but favoured the Sensatyre over the screw on types. They have an additional advantage as they also monitor temperature which can alert you to all sorts of other trouble. Our need is principally for the caravan, so transmission is an issue. Sensatyre can be fitted with a monitor on the caravan, and hard wired to the car to avoid transmission problems. All are expensive, but so is a tyre and rim.

The Jette screw ons monitor temp and press. They have performed faultlessly in the very rough.

I previously had the Tiregards inside the tyre. Performed well too but damaged during tyre removal.

I've recently bought an AVE system off eBay. There are two sellers - one in Canada and one in Portugal. Both communicated very well but the Portugese chap had better prices and much lower postage (the Canadian one wasn't ripping anyone off but postage from North America seems to always be expensive).

The system has internal sensors and will monitor 27 tyres. An external antenna is available but the sellers are confident that for a camper trailer this isn't required. I'll find out in a month or so when we get the camper out for the first time this season.

Everything works well, display is clear, easy to fit (I had a tyre shop fit it but if you have a beadbreaker it's very easy to do it yourself). A wheel balance is required afterwards.

As for after sales service, one of the sensors didn't register pressure. A new one was sent without questions and was in the letter box within a week.

The Canadian seller has a website and now supplies a second generation unit that allows different pressures on different axles. I didn't need this as the camper has similar tyres and similar axle loading so I run the same pressures.

All up was under $300 delivered with 7 sensors. Search ebay with the terms AVE and TPMS, include worldwide as an option. The Buy It Now item (1st gen) from the Canadian seller has recently been reduced in price (below what I paid :( ).

No affiliation etc. etc. just satifsfied.
