Tired of using old school lumpy foam? Now JConcepts is offering Dirt-Tech closed cell foam inserts for stadium trucks and short course trucks. The Dirt-Tech inserts are much more durable than normal foam and have horizontal channels cut on the inside for absorbing big impacts and to help provide more forward bite. These extremely light-weight inserts are precisely contoured for a perfect fit and can be reused multiple times.
The short course inserts have a part number of #3237, the part number for the stadium truck version is #3238, and both are priced at $12 a pair. More details can be found At This Link over on the JConcepts website.

JConcepts Stadium Truck Inserts
The name leading the pack for performance tires and inserts is Pro-Line. They recently released some new Closed Cell Foam Inserts for 2.8″ sized tires so we decided to give them a spin to see how they held up in a hardcore bashing environment. Here is what we found out -
* The closed cell foams weigh more than old school foam. A mounted PL Trencher with closed cell foam weighs in at about 206 grams. The same wheel and tire with a traditional foam weighs in at 180 grams. The upside to the increased weight is that it is easier to pull trick maneuvers like back flips and front flips in the air. The downside is increased rotating and unsprung mass, which can make your electronics run slightly warmer. During our testing we did notice slightly warmer temps but nothing drastic.
* We mounted a closed cell set-up on one side of our review Pro-Line PRO-MT and the same wheel/tire with traditional foam on the other side. We then popped in a 3S LiPo pack and stabbed the gas HARD. The result? There was noticeably less ballooning of the tire with the closed cell insert. Less ballooning makes your truck much easier to drive at high power levels.
* We drove the inserts on a wide variety of surfaces. From the high bit carpet track at the iHobby Expo hall, to the damp high bite dirt inside of Leisure Hours Raceways, to the high bite asphalt at our local CostCo, the closed cell foams drove noticeably better than old school foam. The closed cell foams gave all the trucks a more precise feel and they also seemed to have more mechanical grip.
* We found the trucks we used the closed cells on much easier to drive when doing speed runs. We did speed passes with two different trucks, the PRO-MT and a Vaterra Halix. Both were using MaxAmps 3S LiPo and Castle brushless power. We found the tires ballooned less with the closed cell inserts and were much easier to drive as they neared their top speeds.
Overall – for general bashing we found the Pro-Line 2.8″ closed cell inserts to be a huge improvement over old school foam. The inserts are priced at $11 per pair and you can get more details at This Link over on Pro-Line’s website.

Pro-Line Closed Cell Foam 2.8 Review Gallery
We posted a teaser for Pro-Line’s new 2.8″ Closed Cell Foam Inserts last week, now full information has been released.
Pro-Line knows that a lot of you bashers out there are hard on your gear, so they wanted to give you a more durable option for a 2.8″ insert. Closed cell foam is well known to last longer, which is great bashing, and it doesn’t absorb as much water as a traditional insert, also a great thing for the bashing crowd. The closed cell inserts are also firmer than traditional foam allowing them to perform better under heavy loads and to balloon less on high speed passes. To boil it down, these are perfect for hardcore bashers that run 2.8 sized wheels/tires.
The Pro-Line 2.8″ closed cell foams have a part number of #6266-00, are street priced at $11 per pair, and you can get complete details by hitting up This Link over on Pro-Line’s website.

Closed cell tire inserts have a number of advantages over old school foam. They don’t soak up as much water in wet conditions, they last a lot longer, and they are firmer, resulting in better handling.
Pro-Line is bringing high tech closed cell inserts to the Traxxas 2.8 crowd. These are water safe, reusable, and made to give the 2.8 tires on your truck maximum traction. The set you see in the pictures we have been driving for a couple of weeks now and so far we have been very impressed. We will be putting a lot more miles on them to test durability before our full review goes up in a few weeks.

Short course trucks are still on fire and AKA has just introduced a revised line-up of tires for them. Taking several of their popular tread patterns they have made them wider, thus improving their grip. The tires that got the upgrade are the Handlebar 2, Cityblock 2, Enduro 2, and the Wishbone 2.
Some of the tires also got further upgrades. For instance, the Cityblock 2 had its tread opened up slightly to help it dig in deeper, the Wishbone 2 had its tread pattern condensed for more traction and longer wear, and the Handlebar got slightly taller pins. The new tires range in price from $26 to $39 for pre-mounts.
AKA didn’t forget about upgrading their inserts, they now have asymmetrical cores for more sidewall support. Both their new Red (#33017 soft) and Black (#33016 medium) have a price point of $18. Hit up the AKA Website for more information.

Pro-Line has given us a sneak peak at their new 2WD Buggy Front Closed Cell Inserts. Not much information is known on these guys just yet, but I can say they will be waterproof, reusable, balanced and lightweight. Expect to see them soon on Pro-Line’s website!
Losi is jumping on the closed cell bandwagon. They’ve recently announced a new closed cell foam tire insert for 1/8 scale buggies. These new tire inserts, as is common with closed cell foam, are very durable and won’t break down quickly. You can also reuse them multiple times, saving you money in the long run.
These new inserts should be hitting your hobby shop’s shelves in a couple weeks and will retail somewhere around $17. Check out Losi’s site for a little more info.
Check out these new tire inserts from Italian outfit Veggoplastrc. They’re quite strange looking aren’t they? One of the bullet points for the Airbags (which, curiously, don’t actually appear to be filled with air…) is that there’s
zero centrifugation. Now I don’t know what that means, but it’s a big word and there’s zero of it, so I’m assuming that’s good. Some other features are water resistance, durability, and
perfect balance. The Airbag inserts will also come in three compounds, red for soft, yellow for medium, and green for hard. Right now they’re only available for 1/8 scale buggies. This is a whole new idea for tire inserts, the big question is how well will they work?
