About G-Rengas

Pietarsaaren G-Rengas Oy has been part of Jakobstad since 1987. Over the years, the company has become known by many names – G-Rengas, G-Däck, and to many simply “Keijo’s”. As a family business, we have built our operations on personal service, professional expertise, and a genuine desire to always help our customers.

We, the brothers Kim and Markus, grew up with the workshop as a natural part of our lives. Whenever we were passing by – on a bicycle, moped, or later by car – we would stop in to see what was going on and lend a hand wherever needed. The workshop became a place where we learned the trade, met customers, and watched the business grow, step by step.

When our father Keijo passed away, we took over the company with a clear goal: to preserve everything that has made G-Rengas so valued over the years while carrying the family business forward. We have chosen to continue in the same spirit – with personal service, high quality, and a commitment to always helping our customers.

One of our father’s most important principles still lives on in everything we do: “It’s no problem.” Whatever problem a customer brings us, we always do our very best to find a solution.

Today, we offer a complete range of tyre and vehicle services. With the largest tyre stock in the Jakobstad region, we can often help you immediately, without long waiting times. As an independent family business, we make our own decisions and always put the customer first. 

Every problem has a solution – and we look forward to helping you find yours. Welcome to G-Rengas!
