If you're looking to upgrade your 4WD and get more grip and traction from your tyres, then fitting bigger tyres is a great option. But before taking the plunge, there are a few things you should consider.
First, check your vehicle's manual for the recommended tyre size for your particular make and model. This will give you an idea of what size tyres you can fit without any modifications. Generally speaking, you can usually fit a tyre up to two inches bigger than the standard size without having to make any modifications.
It's also worth doing some research into the type of terrain you’ll be driving on. Bigger tyres will give you better grip and traction, but they also tend to be heavier, which could affect the handling of your vehicle. If you plan on driving in a lot of off-road environments, then bigger tyres could be a great choice. But if you plan on mainly driving on roads, then you might be better off sticking with standard-size tyres.
You'll also need to consider the impact that bigger tyres will have on your 4WD's performance. Bigger tyres will require more power from your engine, so you may need to upgrade the engine to handle the additional load. You'll also need to think about the effect that bigger tyres will have on the suspension and steering of your vehicle.
Finally, you'll need to think about the cost of fitting bigger tyres. As well as the cost of the tyres, you may also need to pay for additional modifications and labour costs.
Fitting bigger tyres to your 4WD can be a great way to get more grip and traction, but you'll need to make sure you consider all the factors before taking the plunge. Doing your research and weighing up the pros and cons will help ensure you make the right decision.
