slf-uk 914 #1 Posted November 18, 2016 It looks like I may need to fit Tri-ribs to the front of one of my Bolens Ride-a-matic’s which has a standard tyre size of 4.00-8. The easy options appear to be Trelleborg T513 from bigtyre https://www.bigtyres.co.uk/4-00-8-4-ply-trelleborg-t513.html or unnamed brand from Allterraintyres (although the pictures appears to show a Kenda tyre) http://www.allterraintyres.co.uk/index.php?main_page=product_info&cPath=1087_1242_1248&products_id=5034 I know I have asked a couple of you for advice previously however I am getting old and have forgotten what was said, sorry. Joseph is concerned that we have to buy the right tyres but I am unsure what he considers to be right or wrong. I would really welcome some advice and if anyone has a picture of either or both of the options above that would be great. Some advice from our US based tyre expert would be cool too, as long as it is not to tell me I have spelt tyre incorrectly Thanks Iain 4 Joseph, Triumph66, nigel and 1 other reacted to this Share this post Link to post Share on other sites

Triumph66 1,256 #5 Posted November 18, 2016 I bought my tri ribs from Big Tryes on Norman's recommendation. They are Trelleborgs tri ribs. 2 slf-uk and HeadExam reacted to this Share this post Link to post Share on other sites
HeadExam 1,783 #6 Posted November 20, 2016 Tubes are important and the rating as well, check out the B,C, D rating system as the ply rating system is fairly irrelevant since they don't rate them by plyes, only by ply rated, I know that doesn't make sense, but it is what it is. I have bought both inexpensive and expensive tri-ribs of the same rating and have yet to much difference. 2 slf-uk and Triumph66 reacted to this Share this post Link to post Share on other sites
slf-uk 914 #7 Posted November 20, 2016 Some great advice as always, thanks guys. At the moment I am trying to keep some enthusiasm up for when I get some time and my workshop back. It currently is currently a store for 12 tractors, a Land Rover and gator. Iain 1 Triumph66 reacted to this Share this post Link to post Share on other sites
Anglo Traction 1,016 #8 Posted November 20, 2016 Got my 4.00-8 Tri Ribs (4ply on offer at the time) from Malpas online UK. Had to send the 4-4.50-8 Tubes back, as they were way too skinny to use on a 3.75" wide Rims. I eventually fitted 5.00 x 8" tubes and they fitted perfectly.

Anglo Traction 1,016 #10 Posted November 27, 2016 Just to clarify the problem I believed I had with the Tubes for these narrow tyres, here's a link to a previous thread on it- -LINK- . Regards 2 slf-uk and HeadExam reacted to this Share this post Link to post Share on other sites

Regards They make a 3.50-8 tri-rib and the 3.50-8 tube is for that tire. The 4.00/4.80-8 tri-rib takes a 4.00/4.80-8 tube. I wouldn't put a 3.50-8 tube in a 4.00/4.80-8 tri-rib, they're tubes, not balloons. 2 slf-uk and Anglo Traction reacted to this Share this post Link to post Share on other sites
