Choosing curing chamber capacity: from 4 to 24 tyres explained

The curing chamber is the biggest single investment in a tire retreading line, and the one that most affects daily output. The most common question is: should one chamber hold 4 tyres, or 24?

It comes down to your daily output. The more tyres a chamber holds per load, the higher the output per hour — but the chamber, floor space and upfront cost also grow. Small shops starting out find a 4–8 tyre chamber more flexible and faster to pay back; high-volume lines chasing throughput choose 12, 16 or 24-tyre chambers.

Next, tyre type. TBR truck tyres are fairly uniform, so load counts are easy to estimate; OTR tyres are large and vary widely, so the chamber's inner diameter is usually sized to the largest tyre.

Heating matters too. Electric heating gives precise, clean, easy-to-install temperature control; steam heating suits plants that already have a boiler and run large batches, with lower running cost. YTON builds both, and can custom-size the chamber and circulation rails to your site.

In short: work out your daily output and main tyre type first, then work back to the chamber size and heating method. Not sure? Tell us your tyre types and target output and we'll advise for free.
