Rendasun Tire Bar Set — 2PCS 37" x 3/4" & 30" x 11/16" forged irons for heavy-duty, damage-free mounting

Rendasun 2PCS Tire Bar set pairs a 37 in x 3/4 in mount/demount iron (model 34645) with a 30 in x 11/16 in tire spoon (model 33220) to speed safe, damage-free tire mounting and demounting on trucks, buses, tractors and passenger vehicles.

This tool combo is designed for pro shops and DIY mechanics who need durable, forged tire irons that resist bending while protecting bead and rim during service. The larger 34645 iron features precision-formed knob grips and a curved profile for secure bead control and a keyed demount tip for second-bead work. The 33220 spoon uses a spoon-shaped end to glide between tire and rim, minimizing pinch points and tire damage. Both pieces are heat-treated for higher hardness and built for repeated heavy use.

How do these bars prevent rim and tire damage?

The spoon-shaped head and the demount iron’s angled tip are made to reduce leverage stress on rim edges and to avoid pinching the inner bead. Controlled contact points and smooth contours let you work the bead without gouging rubber or bending rims.

• Curved demount iron distributes force evenly along the bead edge.
• Spoon end slides between rim and tire to avoid sharp contact.
• Precision-forged knobs keep the iron from slipping mid-operation.

What sizes and tasks are each tool best for?

The set contains two specific sizes tuned to different leverage and reach needs. The 37" x 3/4" iron (34645) gives extra reach and prying power for larger truck and bus tires, while the 30" x 11/16" spoon (33220) offers nimble control for tighter rims and finishing the second bead.

• 34645 — 37 inch length, 3/4 inch shaft for heavy-duty leverage.
• 33220 — 30 inch length, 11/16 inch shaft for precise spooning action.
• Use together for mount + second-bead demount operations.

How durable and safe are these tools for professional use?

Both pieces are integrally forged and heat-treated to higher hardness levels, resisting bending under high torque. Textured knobs and a shaped curve reduce slip, improving operator control and jobsite safety without relying on expensive mechanical changers.

• Integral forging for single-piece strength and toughness.
• Upgraded hardness to withstand repeated heavy use.
• Slip-resistant knobs and ergonomic curves for safer handling.

Can this set replace manual tire changers or specialized machines?

These tire bars are intended as a practical, efficient alternative to bulky manual-changing rigs in many situations, especially where mobility or cost is a concern. They don’t replicate powered machines’ speed for high-volume shops but are excellent for field service, small shops, and occasional heavy-duty work.

• Portable and ready for roadside or farm use.
• Lower cost and maintenance than manual changers or powered machines.
• Best used by trained operators to avoid misuse and damage.

Who is this for: Mechanics, fleet technicians, roadside recovery teams, agricultural and off-road operators, and experienced DIYers who work on trucks, buses, tractors or mixed vehicle fleets will find this Rendasun pair especially useful. If you need rugged, forged tire irons with specific 37" and 30" lengths for heavy or awkward tires, this combo gives leverage, control and bead protection without expensive shop machinery.
