Israel has developed an 8X8 vehicle platform which is designed for a combat weight of 35 tons. While this seems pretty enormous for a wheeled vehicle (and completely opposite of the sort of thinking behind the 8 ton "Combat Guard" prototype), it is probably the logical endpoint to current thinking of wheeled IFV's:
Israel Eitan Armor Personal Carrier uses commercial auto parts for lower cost but has upgraded protection
Israel unveiled the first prototype of the Eitan, a new 8×8 armored personnel carrier developed by the Ministry’s Tank Development Program Directorate (Mantak), as a possible successor for thousands of American-made M-113 Armored Personnel Carriers (APC) Israel has been operating since the 1970s. The new APC is said to be more protected, efficient and affordable than foreign off-the-shelf alternatives, and would be available at half the cost of the Israeli Namer Infantry Carrier Vehicle (ICV).
Eitan uses commercially available automotive components. This enabled the designers to develop an APC that will cost half as the tracked Namer, and less than similar wheeled APCs available in the world market. The hull was developed in the country, along with the weapon systems, survivability and protection systems used. According to Mazliah, the need for a wheeled armored vehicle such as Eitan evolved from lessons learned in recent combat operations in Gaza. The Eitan complements the Merkava and Namer, as it can transport infantry squads on roads, without relying on tank transporters. Eitan has a maximum road speed of +90 km/h (56 mp/h).

Similar to Merkava and Namer, Eitan does not rely only on ballistic armor for protection but uses a combination of survivability systems for to enhance the survival of the crew, passengers, and the entire vehicle. Designed for a gross vehicle weight of up to 35 tons (77,000 pounds), Eitan provides sufficient base protection for common battlefield threats. Using the Trophy Active Protection Systems (APS), the vehicle can effectively avoid high-level threats without proportionally increasing the weight of its armor. To protect the occupants from blast effects, of mines and IEDs, Eitan has been designed with protected, relatively high floor. The tyres are fitted with runflat inserts meaning they can continue to function even after suffering multiple hits. The passive protection provided by modular armor is applied to the vehicle’s front and sides, while equipment modules add to its security. The vehicle will be initially produced at the Israel MOD AFV plant, at an annual production rate of several dozens of vehicles, as is the case with the Namer ICV.
The vehicle is designed as a common, modular platform that can be configured into different variants by replacing hull modules. Variants typically include APC and command vehicles equipped with remotely operated .50 Cal machine gun, and weapon carriers, to be fitted with remotely operated turrets mounting 30/40mm automatic cannon. The turret will also have accommodation for several missile launchers.
While most 8×8 APCs evolved from lighter platforms, the Israeli APC was designed from scratch for 30-35 tons, which is the upper limit of similar designs. All 8x8s are designed for similar roles – they are designed as modular, role configurable platforms, in a weight range of 18-30 tons, each carrying 8-11 troops.
